This is a really cool tool for any avid swimmers in your life. The Swimsense is a training tool for fitness freaks that straps on the wrist and monitors your stroke count, rate, distance-per-stroke and other vitals to improve performance. All these stats can then be logged into a computer for in-depth analysis to help you improve stroke efficiency as well as monitor calorie rates.
However this training tool does not come cheap and will set you back $199.99. Who knows though, it could possibly help you on your way to being the next Michael Phelps
