Havent used them but use something similar at the YMCA.....will use them on our vaca to Puerto Rico 12-9 to 12-18-09

I use these daily to carry on the P.T. exercises I was taught. They are just right.

Barbells end pieces need to be a little thinner to allow more room for hand to hold the barbell.

comfortable, light, yet powerful and
the price was right

I love them. they are awesome, very buoyant  !!!!!

I really enjoy using them on my water aerobics. They really made the difference.
