Exercise balls are both fun and functional and can really spice up your fitness routine. There are balls of all shapes, sizes and weights out there: stability balls for core work, medicine balls for strength and Bosu balls for agility, core stability and more. Fitness balls are generally inexpensive and great fun for at-home workouts.

Medicine balls, which are small weighted balls that you can hold with one hand, are also a great tool for partner exercises. Practice different methods of throwing the ball to your partner and you’ll feel it in your arms, shoulders, core and back.

Soccer balls, volleyballs, basketballs and baseballs are also great fitness balls, so don’t be afraid to get your game on and burn off some calories while you have fun playing competitive sports.
