How to Do Crunches So They Actually Work Your Abs

If you're not a fan of the floor, the standing ab march will help strengthen your core just as well as crunches. Standing ab work is also good for mobility, stability and coordination. This ab march is just one variation to try out:

• Start in a neutral standing position with your arms by your side.
• Engaging your abs, bend your knee and raise it up to your torso. Pause at the top of the position, and lower back down to the ground, repeating on the other side.
• Aim to march for 30 seconds. For an additional challenge, you can also hold a dumbbell overhead as you march.
