Felt like I had no propulsion which is exactly what these are intended to do. They are def making me a better swimmer by correcting my form

Using the PT paddles helps me feel the difference between being balanced and unbalanced in the water.  Compared to swimming with fist, these paddles allow you to keep your hand in a normal position and still feel the water... but you can''t anchor onto the water with your hand.  Highly recommended.

Great product for teaching holding water through stroke cycle.

I swim an hour every day for exercise and bought these because I wanted to improve my swimming technique. For a while, I used to do a fist to simulate the same idea, but these work much better. The biggest advantage I first noticed was that they push your elbows higher, which is something I really struggled with. But there were other good things, too, like better body roll, using my lats and core muscles instead of relying heavily on shoulder muscles. Long-term, the biggest benefit is in avoiding shoulder injuries, both from bad technique, which these help you correct, as well as from relying solely on shoulder muscles/overworking them. I have noticed a big difference in how my shoulders feel. And I noticed the difference almost instantly, within a day or two after I started using these, which is amazing. If you know what you're doing, these are a great tool. If you are just starting out swimming or getting the basics of the freestyle stroke, I would recommend that you stay away from these until you become more advanced as these will frustrate you, as is evident by other reviews here. The only minor downside/design flaw I found with these is that the rubber band in the middle is a bit uncomfortable, so I decided to take it off altogether and it works just fine. Other than that, I think it's pretty well designed (well, so far, anyway - I've only been using these for a few weeks).

Put these on your hands and swim. Without proper body roll and  mechanics you won't go anywhere. These also protect your shoulders.  If you know how to use them, and are willing to push yourself -really push yourself, you will improve. If your mind is closed, or you're lazy -don't buy them.

Feedback from our athletes has been tremendous.  Greatly helps improve early vertical forearm with hip driven and shoulder driven freestyle.
