Two low-friction discs that turn a flat floor into a resistance tool. Put them under your hands or your feet and every movement becomes a controlled slide, so the middle of the body has to brace the whole way through instead of only at the end.
They work on wood, carpet, rugs and tile, so one pair covers the living room and the gym floor. Each disc is small and flat enough to disappear into a bag or a drawer.
Use them for mountain climbers, pikes, hamstring curls, reverse lunges and chest flyes, or as part of conditioning, physical therapy, dance, yoga and balance training. Set of two.
