How to do it: Stand holding the back of a chair with one hand. Place your feet in a V position, toes should be about 4 inches apart and heels stay pressed together. Bend your knees and lift the heels a few inches off the floor. Then, lower your hips until you feel your quads intensely working. Pulse up and down.
10-15 pulses up and down completes 1 set; do 3 sets.
