Reverse Lunge With Front Kick

Start from a standing position with feet together. Step back with one foot and bend both knees to a 90-degree angle while keeping the chest up. Push through the front heel to stand up and do a front kick with the back leg. As you are doing the front kick lean back slightly to engage the lower abs. After you are done with the front kick bring that same leg back to a reverse lunge and repeat.

Keep your abs tight to improve your balance.
