Crunches are one of the most basic and effective ways to work your core muscles. But if you’re doing them right on the floor, you might find yourself modifying moves in order to avoid bumping your spine on the hard ground and consequently inhibiting your own progress. The solution: try a yoga ball.
The soft, bouncy ball gives you solid support and makes it way easier to complete the moves as they’re supposed to be done. Plus, you'll use your legs and core to stay balanced on the ball, making your workout even more effective.
Watch to find out how to use the yoga ball to work your upper and lower abs.
