What's the difference between a slam ball, a wall ball, and a medicine ball?

Per the r/crossfit consensus we read, a slam ball is rubber, sand-filled, and designed for zero bounce — you throw it hard at the floor. A wall ball is larger, softer, and lighter (the CrossFit standard is 14 lb for women's RX and 20 lb for men's) so you can throw it 9–10 feet at a wall target. A traditional medicine ball is firmer with a moderate bounce, used for partner tosses, rotational core work, and rehab. Buy for the movement you'll actually do most.
