SPRI Deluxe Vinyl Dumbbells, 3 lb Pair, Lime Green

I use these while rebounding for added resistance. The "bounce" in rebounding creates a lot of momentum, which is hard to control and maintain proper alignment. So in order to control movement and not just flail the arms overhead, or away from the body, I use super light weight against the natural momentum.

I purchased SPRI vinyl dumbbells (8,10,12,15 lbs.) for a friend about eight months ago. She enjoys working out with them three times a week. She's trying to gain weight unsuccessfully but I have noticed her improved muscle tone. While she weighs only110 lb. to my suprise she is going to need the 20.lb dumbbells soon for her sqauts for a continued challenge. 11/08/2016. She is 48 yrs. and I'm 50 yrs. young.
