Review on Contour Paddles Training Adjustable Swimming by Gavin Dunne

I was skeptical about adding them to my swim workout. but after the first application i can feel the difference. I mainly use them for freestyle crawling and I can feel the difference on the back shoulders, buttocks and arms. Freestyle crawling strengthens your arms, but adding them gave me more lift and a smoother punch. Pushing the water down and back is very effective, but it's impossible to get the maximum effect with just your hands, no matter how tightly you clench your fingers. The straps have just enough tension to keep your hands in place, but there's no rubbing or discomfort. Lightweight and compact, they can be easily slipped into a pocket.
