Swimsense New Firmware Released – 1.0.1.6

Since the release of Swimsense® in December 2010, we understood that a key development goal was to improve the time the Swimsense® would last on a single charge. For all of our techie Swimsense users, you probably understand how difficult it can be to optimize software to consume less resources while not degrading the functionality. It’s a tough problem but one that we’re happy to say we’ve made significant progress on.  As of today, we have released a new version of the Swimsense® firmware (v1.0.1.6) that improves the battery life as follows:

Previous Battery Life Times
Not in Swim Mode:  20 hours
In Swim mode:  8 hours

New Battery Life Times
Not in Swim Mode:  150+ hours (about 1 week)
In Swim mode:  12+ hours

Looking ahead, we are working on a number of new features for the Training Log.  These include:

  • ability to export workout information to Facebook and Twitter
  • ability to make workouts public/private allowing you to share your workout details page
  • integration with 2Peak and SportTracks
  • a new version of the Swimsense® Bridge that contains a number of minor enhancements

To keep up to date on new releases and what happening with Swimsense follow swimsense on Twitter.

Sucking Wind (in a good way)

What’s normal?

For most swimmers, the part of their swimming technique most flawed is…well…everything done while trying to snag that next gulp of air and then recovering from the experience over the next stroke, or two, or three. Yet, because this is repeated thousands of times each workout, the struggle for air and the attendant loss of performance – head-lift, hip-drop, neck craning, pushing down on the water instead of making a proper catch, etc. – eventually begin to seem “normal” to the neuromuscular system and soon become habit. Repeating this every second or third stroke means that the swimmer simply cannot establish sound fundamental stroke technique habits based on rhythmic motions around a well-postured core cutting javelin-straight through the water. This is because it takes at least one additional full non-breathing stroke to fully recover balance. And, depending on how out of balance the swimmer gets, it may take more like two or three non-breathing strokes to recover balance. This means he is forever locked in the vicious cycle of:

  1. during one stroke, using a going-for-air motion that gets him out of balance,
  2. then during one or more subsequent strokes, trying to recover from the most recent awkward or destabilizing breathing motion,
  3. then repeat with no opportunity for uninterrupted well-balanced swimming – the only kind of swimming from which good habits might be built.

Your vicious cycle

So if your current going-for-air habits destabilize your balance, even a little, you too have some form of this cycle at work in your swimming. And your neuromuscular system, and maybe even your brain, accept this as “normal” (and worse, maybe even think of it as “OK”). Sound good to you? I hope not.

The solution:  A snorkel

Try a snorkel. Yeah…I know…you’re flashing on images of grandpa in big ol’ shorts, sporting a scuba mask, a plastic tube flapping around by his ear, swimming turtle-crawl in the slow lane and doing face-in-the-water U-turns a couple yards shy of each wall.

But what you need is a snorkel designed specifically for swim training; one that mounts in the center of your forehead and curves up from your mouth, runs in front of your nose and over the top of your head to allow for a proper head position while not getting in the way of your strokes and not creating useless extra drag.

How it helps

A training snorkel eliminates the distraction and complication of turning the head to breathe, giving you an opportunity for uninterrupted focus on, and repetition of, other aspects of swimming. Following are a few areas, vitally important to highly effective swimming, where the snorkel excels as a training aid:

  • Learning to maintain the tight line of good aquatic core posture while simply inhaling. Keeping your tight line is greatly complicated by the action of inhaling, especially when taking deep breaths. The secret here is to expand your lungs to the sides and back instead of heaving your chest and letting your ribs pop out. Use of the snorkel gives you great feedback about what happens to your tight line as your diaphragm, chest and back muscles work to fill your lungs. By not having to turn your head to breathe, you can isolate and refine your swimming-while-holding-tight-line-while-inhaling skills…something you simply cannot do without a snorkel. Using the snorkel on long, high-intensity sets that require full ventilation gives plenty of time to work out postural details while forming strong habits that elude most swimmers who insist on always breathing the old-fashioned way. (See the What Floats Yer Boat?, Critical Mass In The Twilight Zone, and Claim Your Lollipop articles for more about “tight line”)
  • Eliminating ups and downs of your moving vessel. Imagine rowing a boat that has lots of up and down motion where the front end and back end alternate elevations. Your job as pilot and power source is clearly a lot tougher than that of the other guy whose boat skims along on an even keel. So too with swimming. If you watch nearly any non-elite swimmer closely you’ll see that either the head or the entire front end of the body has some upward motion on each breath. And, consequently, the hips tend to dip toward the bottom at the same time. A snorkel allows you to learn what it feels like to swim distances without up and down motions of your head or hips.
  • Keeping your central line on the desired line of travel. Even with good core tension, it is easy to stray away from the chosen path while swimming. You have no accurate visual feedback about the line you are really traveling, except when keeping your eyes firmly focused on a thin line directly under your nose. Most swimmers, including you, traverse a zigzag line to some degree without being aware of it. This is most often the result of pulling the head and/or upper body toward the breathing side each time a breath is taken. Once that zigzag becomes a habit, it feels “normal” and is hard to quit. Yes, you can spend some time doing no-breather swims in order to spot the problem. But only a snorkel gives you enough uninterrupted straight-line visual feedback to really feel what it is like to swim continuously in a straight line – a first step toward correcting the problem.

Even if right now you think you do not lift your head or upper body to breathe and, consequently, that your hips do not drop at all while you are sucking in air, once you spend some time with a snorkel you will likely realize that your original self-assessment was wrong.

How to start using it

Even if you are a veteran of conventional snorkel use, a training snorkel takes some getting used to. Here is a progression that starts from scratch and builds to full-stroke swimming. People of different ability and experience levels will benefit from different amounts of time and experimentation in each step. If in doubt, spend more time on a step rather than less.

  • First, while wearing the snorkel, simply put your face in the water and breathe through the snorkel enough to get comfortable. Experiment with different size breaths. People who’ve never used a snorkel, or who’ve only used snorkels with a face mask that covers their nose, are often surprised to find that they do not know how to keep from inhaling through their nose, thus getting a snoot full of water every time they try to inhale. While this can usually be overcome through patient practice, a nose clip can quickly render the issue moot.
  • Now spend some time doing easy kicking with fins. The general idea is simply to kick from your hips with fairly straight legs instead of kicking from your knees. If your knees bend it should only be as a reaction to water pressure, not because of a direct action of your muscles. If your kick involves contracting muscles to bend your knees, you are lost and need to start over. (If this concept is new to you, try holding your legs stiff as planks. Yes, this is a simplification, but does express the most important aspect: don’t build your kick around bending your knees.)
  • Next, learn to purge your snorkel of water. Do this: inhale, go under water deep enough to allow the snorkel to fill with water, then resurface and blow out briskly to purge the snorkel of water. This will come in handy after turns and when you make mistakes that swamp the snorkel.
  • Next, while still kicking easily on the surface, work on assembling your tight-line posture and balance (see the article, What Floats Yer Boat?), holding both as you breathe. It is important to spend time working with the full range of ventilation. Breathing deeply while holding the abdominal tension required for tight-line posture is complex if you aren’t used to doing it. Remember, expand your lungs to the sides and back instead of heaving your chest and letting your ribs pop out.
  • Add core rotations to your kicking (see the What Floats Yer Boat?, and Bottom Up Swimming articles). The idea is to build a good feel for what it means to remain 100% horizontal and keep your tight-line posture fully engaged as you cruise the length of the pool. Done properly, the back of your head, shoulder blades, hips and legs remain right at the surface at all times. Be aware of a patch of flesh on each thigh, just beyond the edge of your suit. As you rotate down the lane you want to have one of these patches, or the cheeks of your butt, exposed to the air at all times. Anytime you don’t have one of these exposed to the air there is a problem with posture. (Note: the “patch of flesh” thing isn’t operative if you are wearing a jammer suit.)
  • Next add strokes to those rotations. Start with a single-arm stroke cycle, several rotations, then another single-arm cycle. Go a length using one arm, then a length using the other, then a length alternating arms.
  • Next, execute cycles of two strokes (one with the right arm and one with the left), several rotations, and another cycle of two strokes. Alternate which arm goes first in each cycle of two strokes.
  • Then sets of three strokes, with several extra rotations between each set. Alternate which arm goes first in each cycle of strokes.
  • Then sets of 5 strokes, etc.
  • Then full-stroke swimming.

(See my book Fitness Swimming, 2nd Edition for lots more detail on this progression from simply kicking with core rotations to swimming some, then progressively more,  strokes powered by leg-driven core rotations.)

The real payoff

The greatest value in the snorkel comes from wearing it through a large portion of your full-stroke swimming – 50% or more (and some days maybe even 100%) of your workout swimming. This is where real habit-building happens. You want to make continuous tight-line, impeccable balance and javelin-straight core your “normal” feelings (as opposed to something that involves no posture or intermittent posture and up-and-down and/or side-to-side motions). Creating new habits requires lots of time and repetition. Overwriting current bad habits with new good habits requires even more time and repetition. So lots of time spent swimming with the snorkel will have big payoffs in the habit department.

Then, for short segments (in the beginning, just a length or two), remove the snorkel and swim with breathing motions. Your job here is to have great awareness of where your head, lead arm and hips are while breathing without the snorkel then compare and contrast that to swimming with the snorkel. After much time spent swimming with the snorkel it should now be much easier to sense and identify balance, posture and timing errors that result from your going-for-air motions.

Because the snorkel has allowed you a bunch of uninterrupted time focused on good posture and balance, you will have new knowledge and skills (and, eventually, habits) to apply in correcting those going-for-air errors.

Shortest path

What you eventually want is to be able to count on a zero-head-lift, zero-loss-of-balance, zero-performance-hit breath any time you want air. Learning how to get, and making a habit of, such breathing motions is much easier to do when you have the right foundation ingrained in muscle memory – and the shortest path to such a foundation is traversed with the training snorkel firmly attached.

Added bonuses

Darn near any other swimming skill you might desire is easier to learn and habituate when you use a snorkel to remove the distraction of “how do I get air”. And when your workout calls for kicking drills you can eschew the kickboard (which teaches you to kick uphill instead of in a straight line) in favor of the breathing tube – you’ll go faster and be creating better habits.

Where to find it

Finis Inc. is the only company currently offering a proper training snorkel. They have several to choose from. I strongly recommend the Swimmer’s Snorkel which you can likely purchase at your local swim shop.

Once you get really good using the Swimmer’s Snorkel you may derive increased benefits from the Freestyle Snorkel, also offered by Finis Inc. This snorkel is designed specifically for freestyle swimming, and is particularly beneficial at higher speeds. It requires a higher level of skill to use properly but promotes further skill refinement in more-skilled swimmers.

(Warning: If you make the mistake of saying to yourself, “I’m just going to shortcut the learning process and get this snorkel as my first training snorkel” you’ll likely just end up frustrated and unhappy. Get and use the Swimmer’s Snorkel first – then, after maybe a year of using it, consider the Freestyle Snorkel.)

New Swimsense Firmware (v1.0.1.5) Released

Working closely with our partner SportSense, we are pleased to release a new update for the Swimsense watch.  This update (and any future update) is compatible with all Swimsense devices. So even if you bought you device 3 months ago, you will always have the latest and greatest features. Simply connect your watch to your MAC or PC and launch the Swimense Bridge application. You will automatically be prompted to update your Swimsense with the new firmware.

Here is a breakdown of the new updates in v1.0.1.5:

  • Continuous Save

Never lose your workout information. Even if the battery dies during your swim, the device will auto-save your data.

  • Improved Stroke Rate Calculation

Our previous Stroke Rate calculation included the time that you spent pushing off the wall, before you started stroking. By eliminating this ‘non-stroking’ time, we can calculate a more accurate Stroke Rate.

  • 24 Hour Clock

You now have the option to set the watch clock for AM/PM or 24 hour

  • Miscellaneous Features & Bug Fixes
    • Fixed random buzzer bug that occurred when clearing watch
    • Adjusted ready-to-swim display to properly read as ‘meters’ when device is configured to meters
    • Fixed issue where watch does not save weight setting when set in KG
    • Removed the charge symbol from the battery icon after disconnecting the device from a USB wall charger
    • Removed the rest time from the Interval History display
    • Made it so you can now increment your Age and Weight configurations by units of 1 rather than by units of 5

We are also scheduled to release another firmware update soon which will improve the battery life of the Swimsense. Today the watch supports 4 hours of swimming use and 20 hours of non-swimming use on a single charge. Our intent with the new update is to double these hours.

Keep tuned to the FINIS Blog where you can learn about other new Swimsense updates like how to export data or integrate with TrainingPeaks.

Swimsense – A Triathletes New Best Friend

Hey Triathletes, I got one word for you: SWIMSENSE™. You gotta go and get this new toy and add it to the arsenal. Why? Give me 5 minutes.

As a coach and Pro Triathlete, pacing is crucial in any open water swim. Most newcomers to the sport and those that battle with the swim, have major problems when it comes to pacing over a long swim distance. Out in the open water there are no coaches to whistle you along, no lane ropes and turn walls to rest on, and no clocks that tell you the splits. You have to learn to do it yourself. Pool swimmers learn over the years on how to measure their performance in a pool that is of standard size. What happens when you need to swim 1.9km or 3.8km with no yardsticks to work off? You buy yourself a Swimsense and train with it, that’s what.

I have taken a few screen shots and used myself as a guinea pig. I did this morning’s workout as a pre Ironman South Africa 70.3 warm-up (which takes place Sunday the 23rd). 30 x 100m repeats on 1:30. Normally I would swim more repeats on a 1:20 interval, but I’m getting ready for my race.

Take a look at the “stroke count” charts for starters, both the pie chart and the bar chart of the 30 x 100 repeats. My stroke count remained consistent at 20 strokes per length (10 stroke cycles) for almost all the repeats. That is a pretty solid tempo.

Then we take a look at my pace chart. All the 100 meter repeats hover between 74 and 76 seconds with only 1 straying out o

f those parameters. You will also notice that my concentration levels seemed to slip a little from #21 to #27 before I regained my composure and focus.

This is the type of pacing you will need to swim a solid ironman swim or any open water swim distance for that matter. Swimsense is an incredible triathlon tool when it comes to honing one’s swim pace skills and is definitely a MUST for any triathlete looking to swim better and more efficiently.

I have cut and pasted only 6 of the hundred meter repeats to show you the pacing measured over each 25m. You will notice that the 1st and 3rd 25m are always fastest per each hundred meter repeat, The reason? Simple. The pool I use has a strong current flowing in one direction and this is evident with my pacing (although stroke count still remains consistent).

Anyway, a lot of jargon and times/splits etc. The bottom line with this workout is to show you what the Swimsense can do for you in your search for the perfect triathlon swim. An absolute winner in my books.

For the Aspiring Fitness Swimmer: 3 Easy Ways to Start Swimming Smarter (and having A LOT more fun!)

Do you dread every time you get to the pool because you know that you will swim 40 laps, back and forth, staring directly down at the dreaded black line? Does it feel like you reached a plateau where you simply can’t improve any further in your swimming? If this is you, I’d like to give you a couple of tips that are sure to help break up the monotony! And it’s sure to help you improve your swimming at the same time. Too easy, right?

Step 1: Start Counting Your Laps in Between Rests

Simple enough right? If you stop on the wall between lap 4 and lap 8, you just swam 4 laps and thus 100 yds (in a 25 yd pool). Instead of counting your total distance, start looking at how often you stop on the wall. Swim normally during one of your sessions and try to keep track of how many times you stop. From there you can work on swimming specific distances. If your goal is to swim 80 laps in each swim, why not try swimming 10×8 laps (or 200s)? Or maybe try 5×200 and 10×100. Notice how your body reacts to the different amounts of rest.

Step 2: Keep Track of Your Times

The next big step is to start keeping track of your times as you swim one of these predetermined distances. This gives you the ability to gauge your improvement. How do you find your time? Most pools have pace clocks installed which will show seconds and minutes. Try getting your times on similar distances across a couple of weeks and you will now be able to assess how well you are swimming. I guarantee that you will see yourself improving as you try to beat your previous personal best!

Step 3: Fartlek Workouts for Swimming

Fartlek “speed play” is the revolutionary training system developed for running in the 1930s that was applied to swimming in the 1960s, with tremendous results. It focuses around putting stress on the aerobic energy system by varying the speed and intensity throughout the workout. This means in simpler terms, that you will go fast in certain parts of your swim and you will go easier in other parts. Most of the swim workouts you now see are designed around this concept, but it can be a lot simpler than that. Try swimming the first part of your workout easy to warmup. Then try swimming some faster shorter distances, pushing yourself to swim harder than your typical effort level. Make sure to take extra rest in between each of these shorter intervals. Despite the extra rest, you will notice that you are in fact breathing harder and getting a better overall workout.

FINIS Announces Official Sponsorship of Jason Lezak, Gold Medal Olympian

Jason Lezak, one of the most decorated Olympic athletes specializing in freestyle races and relays, gives FINIS® Hydrospeed Velo Swimsuit and other technical swimming products his full endorsement.

FINIS®, the Worldwide Leader in Technical Swimming Development and provider of select training equipment for the U.S. Olympic Swim Team, is pleased to announce their official sponsorship of Gold Medal Olympian, Jason Lezak. As one of the most decorated Olympic athletes in history, Lezak specializes in freestyle races and relays and has won a total of seven Olympic medals. Lezak will use a multitude of FINIS® products to train with including FINIS®’s latest high performance tech swimsuit the HydrospeedVelo and their highly anticipated SwimsenseSwim Performance Monitor.

“We are very proud to be working with an athlete of Lezak’s caliber. Elite athletes have trained with our equipment at an Olympic level for years,” says John Mix, FINIS® CEO and President. “FINIS® is now bringing the latest in technology to competition swimwear with the HydroSpeedVelo, a high performance tech swimsuit andwe are thrilled that Jason Lezak will be one of many athletes to use it.”

Virtually unknown in the swimming world in 1998, Lezak lit up the 1998 U.S. National Championships winning his first National Title in the 100 Freestyle…and that was only the beginning. Lezak went on to win a Gold and Silver Medal at the 2000 Olympic Games. In 2002, he dominated his opponents becoming the #1 ranked sprinter in the world. At the 2008 Olympics, Lezak won the Bronze Medal in the 100 meter Free. He won Golds on the 4 x100 Free and Medley Relays, both relays shattering the world record. In the 4 x100 Free Relay, Lezak anchored a come from behind win by swimming the fastest relay split in history, preserving Michael Phelp’s quest for a record-setting eight Gold Medals at the 2008 Olympics. The 4×100 Medley Relay, which he anchored, was Phelp’s final eighth Gold Medal.

Lezak will be one of the first to compete in the HydrospeedVelo Swimsuit, a high performance tech swimsuit approved for competition by FINA, the governing body for competitive swim. The Velo, available for both men and women, features smart compression racing technology with minimal permeability and blended materials that provide superior friction reduction limiting resistance on the body. The panel construction allows compression and freedom where you need it most, and the suit is calendared which is a technical heating process that produces an ultra smooth and lightweight surface. “I look forward to working with FINIS® and training with their high quality high performance products,” says Jason Lezak, Olympic Gold Medalist. “FINIS® has a long standing reputation for designing technical swimming products, as an Olympian I look for the best equipment available and I know this partnership will accomplish that.”

Sculling Drills help improve your technique and feel in the water

Mark and I often cite improving stroke technique in swimming as being the single easiest and quickest way to see improvement. One of the best ways to begin improving your stroke technique is to improve your body awareness and especially your awareness of your hands. Sculling is a type of drill in which the arms and hands engage in a sweeping motion, applying pressure to the water. There are many types of sculling and each type replicates a sweeping motion of one of the four stroke types. In the next few weeks, I will be discussing some of the different types of sculling and how they can be used to improve your stroke technique. Let’s get started!

This week features the Middle Sculling Drill. As you can see from the video, to perform this drill correctly, you should keep your elbows high and sweep your arms in a lateral motion not unlike a “wind-shield wiper” sweep. You should feel your forearms and hand applying a slight pressure behind you on the water. Use this sculling drill to work on the in sweep of butterfly and breaststroke. The drill also can help you establish better “feel” in freestyle. Note that we used FINIS finger sculling paddles so that we would be able to have an additional “feel” during the drill.
