Before I started using this, I looked up videos from other users on how to use it properly. None mentioned that you have to wear it tightly around your waist, so that is key when using this product. The weight has to have something to "pull against" to spin around. You will use your knees. To use, you basically have to swing the weight to get it going and then bounce from side to side on each foot. The faster you bounce side to side, the more tension there is to keep the weight moving. I did notice my cardio increasing as my heart was beating faster when I was done

I bought these for working out to stay cool and not drenched in sweat, yes women sweat. They do their job and have kept me cool through workouts. I use these for biking also and everyday use when it is too hot out. Did not shrink in wash and did not fade or bleed on other clothing during wash either.

Love the board, has helped with proper form and gives me a full range of motion for each exercise.

this is a very nice bench! Easy to assemble, super sturdy, and fairly comfortable.
