So one of my nieces gave me one of those elastic resistance devices for strength training recently. I'm not sure if she bought it for me or herself actually, because she spends a whole lotta time on it.:rolleyes:

But...I really dont think its as effective as free weights...GRAVITY!

Not sure why.

Any similar experiences here???

Not really for "strength" training, per se. If you want to add a little resistance to simple motions, I don't see the harm.
