I'm using them to improve upper body strength and help my bad rotator cuff.  They are a tough work out, I use them for free style and take them off for other strokes.

Thanks for the accurate sizing description.  They fit and work great.

TYR should go "green" and offer replacement straps.  The chlorine
weakens the straps and you are forced to purchase new paddles as opposed to straps.  You can't recycle the hard plastic.

Otherwise love the paddle. .

I use these paddles to strengthen my arms and improve performance. I find them very useful. My performance has improve after working with the paddles for awhile. More endurance.

One of my main workouts is a 10x200 pull. I didn't have any shoulder pain and my lats were burning like crazy after the workout. I followed the size chart, I'm a beginner master and got the (s) yellow size. They "look" big but the feel is perfect.

I bought these paddles for my daughter after researching the best paddles on the market.  She is new to using paddles and still needs all the bands on them.  The only issue we have is that the elastic bands are all the same size, and as a result, the wrist band tends to cut off circulation in my daughter's hands.  Wish they came with a few bands that were larger just for that purpose!
