I use the hand bars in water aerobics.  I lift weights regularly and used "heavy" hand bars at a different pool.  I expected a similar experience with these hand bars.  However, they are really, really heavy in the water.  I am going to order a set of medium hand bars.  It would be very helpful to have some sort of comparison of the "weight" (resistance) to land weights to use as a guide.  These heavies seem to me to be comparable to 20 pound land weights.  But they are very buoyant and can substitute for some of the uses of a noodle.

In the pool every day. These give me the best workout, yet! Start slowly, as they could cause pain in weak joints, as my wrist

I use the weights in my water aerobes classes, I think  with the weights I get a lot more out of the classes, i am not very good at treading water, with the weights I''am able to work on the full body crunch and all the lower body. The weights are heavy, the stronger you get the more you will like them.

We use these in our water aerobics class. They are great except that they are too heavy for my wife and we need to purchase another set for her.

Great product to build musle tone while swimming. Love it.

When I do aqua aerobics, it's as important to me to incorporate resistance and strength-training, too, for a full-body workout. These buoys provide just what I need to challenge myself at even greater levels than the buoys provided at our local pool.  I am thrilled with this purchase, and look forward to all the health and beauty benefits that will accrue as a result of using these weights!
