Many of us have used medicine balls in the past for strength and endurance training. The TRX Medicine Ball is a handcrafted medicine ball that can be used for wall ball throws, squats, sit-ups, and other popular moves. It is available in 4 to 12 pound versions.
Want something heavier? You can get the 14 inch version that has up to 20lb weight options. The soft construction goes easy on your body as you perform moves.
