Bulgarian Lunge

Place one foot on a bench or chair behind you. Make sure there is about a 12 inch of space between the knees. Lower yourself down until the front knee is at 90 degrees. Hint: Think about lowering the back knee to the floor. Push up through the heel on the front grounded foot. Repeat. If you have trouble balancing hang on to another chair or the wall.

This exercise challenges your strength and balance at the same time.
