- Start standing tall with your feet about hip-width apart.
- With control, step your right leg out to the right, coming into a lunge. Your left leg should be straight, and there should be a bend in your right knee.
- With most of your weight on your right leg/foot, push through your right heel as you simultaneously drive your right knee up and off the ground. Keep your foot flexed (don't point your toes down).
- Be sure to keep a 90-degree angle at your right knee and right hip — this is the part of the exercise that fires up your abs.
- Return to a standing position.
- This counts as one rep.
Tip: If it's hard to keep your balance, you can return to the starting position and then lift your right knee up, instead of doing this in one motion.
