I keep these hooked to a door knob in the kitchen where I''m reminded to spend a few minutes daily working on a high elbow catch and pull through. The paddles add a realistic feel to the exercises for my hands and wrists. The red model is rated medium hard and offers a little more resistance than I get from my stroke in the water, which is what I wanted. However, I wouldn''t want any more resistance.

there is a huge difference using cords where your palms emulate swimming...that is very unique and crucial to stretchcords w/ paddles
but you sent me black cords which are too strong...  i ordered blue ones!!!

I''ve got 2 teenagers using the green paddles.  This seems to be a good amount of tension.  My son can stand further back to make the pull harder and my daughter can step closer to the front for a lighter pull.

Ver;y sturdy.  Easy to use.

These paddles are great for workouts out of the pool. If you can do perfect technique while always having tension on the chords, it can benefit both your strokes in the water and your strength. I use it all the time when I have hip or knee injuries so I can maintain or even strengthen my upper body.
