7. Stair hops

For this exercise, you'll perform mini-squats.

• Stand tall with feet shoulder-distance apart on the lowest step.
• Face toward the bottom of the stairs.
• Lower your hips down and back by bending at the knees. Be sure to engage your stomach muscles. Jump forward off the step with both feet.
• As you land, bend your knees to control the landing. Work on landing softly.
• Steady your balance by swinging your arms forward.
• Keep your knees in line with your feet. Don't let the knees collapse inward as you land.
• Return to the starting position and repeat.
