I noticed that this is the brand my Physical Therapist was using so I bought a pair for myself. Nice to have peace of mind that it’s able to adjust to what my body needs as far as the amount of tightness. After 3 weeks, my left knee is getting less and less achy because my left quad has improved so much over that short period of time. I’m also noticing a very quick progression in strength and size there and when I use the arm bands to do push-ups, both in my arms and in my chest. This has revolutionized my martial arts training by helping me get past the weak foundation from my knee and has helped majorly with kata and normal everyday techniques. Because this tech was developed originally in regards to older people, I’ve been able to recommend it to my aging parents to help with some of their muscular problems, to help give them a firmer foundation for everyday life. Great for people who don’t have the time to get to a gym or don’t have access to heavier weights. There are lots of pointers and tools on the SmartTools website for exercises and safety. Thanks SmartTools!
