@protect_the_om: OK, this wrist ball is actually quite fun! I love that you’re stabilizing the joints in the shoulder as well as in the wrist. You’re toning the arms and the core at the same time and getting a great upper body workout! Merach created something pretty cool with this wrist ball. #WristBall #merach #athomeworkout #shoulderstability #upperbodyworkouts @MERACH
