Essentially a flexible rubber ring with handles, the Stamina Pilates Magic Circle powers up your workout by providing added resistance. Squeeze it between your thighs and it engages both legs and abs; do the same thing in your hands and you’ll work arms and abs. Press it against your hip using one arm and you’ll get killer deltoids and triceps. $27 with DVD workout at pilates-ring.net.
