Make sure you’re using the right size—your feet should reach the floor and your knees should be bent at ninety-degree angles when you’re sitting on it. Exercise balls are great for improving balance. The core muscles have to do a lot of work when you’re balanc- ing on the ball. Medicine balls are another option for core workouts.

BOSU stands for “both sides up.” It looks like a ball cut in half and stuck on a flat disk. Both sides can be used for exercising. The rounded side gives support for exercises like planks, while the flat side lets you practice balancing as it wobbles with the round side down.

The captain’s chair is also known as a power tower, or a vertical knee raiser. This machine is great for strengthening the rectus abdominus muscles. The captain’s chair has supports and grips for your arms and
