They work well and the resistance is accurate.Helped improve my wrist strength and my grip when using barbells and dumbbells during workouts..I'm happy with this purchase.
This ring provides the tension necessary to target inner and outer thighs and make them burn (if you want them to). I like that you can work upper and lower body with it.
So I ordered one for my home which allows me to do some of the mat floor exercises. One of my previous classes used a metal ring which is not as flexible. Even my husband who is a regular exerciser has adapted it for some of his flexibility exercises (he's a golfer). Have taken Pilates from several trainers. My current trainer uses a Pilates ring.
It doesn't work as well for upper back because it moves around if you place it behind you or on the floor, so you will need a 2nd person to work your upper back. They do love when I roll it on them too though, haha. I can just sit on the couch and roll it up and down my leg. I bought this as a cheaper alternative to foam rollers. I also place it on the floor and use it on my feet, which, as a runner, feels really good. My dogs seem to think this is a chew toy, so I have to keep it out of their reach. I needed something that dug a little deeper as well. This massager works great on my IT band and lower back.
This is my second purchase, love the size and overall bag. First bag lasted me about 2 years of almost daily use before main zipper broke.
