Medicine balls are weighted to add resistance to any exercise, from crunches to squats to shoulder presses, making them a great stand-in for dumbbells. Most of them are around 13 or 14 inches in diameter (about the size of a standard volleyball) and are available in a wide range of weights, from one pound up to 30 pounds. They're usually made from rubber or nylon, and some have handles for easy gripping.
With traditional dumbbells or barbells, you have just one option: to lift and lower the weight. Medicine balls have the added option of being thrown, which can add a new level of explosiveness and versatility to your workouts. They're highly effective in strengthening the entire body, especially the core muscles, while allowing for more range of motion in the joints.
When choosing a weight for your medicine ball, a good rule of thumb is to shoot for 30 to 50 percent of whatever your maximum dumbbell weight would be for one repetition. For example, if your max is 12 pounds for one bicep curl, you might want to start with a six- or eight-pound medicine ball. You might also want to vary your weight by type of exercise: lighter for faster, more explosive movements, and heavier for slower, strength-focused exercises.
