Modified plank variations

For more core-strength exercises, try these variations on the modified plank:

• Lie on your stomach. Raise yourself up so that you're resting on your forearms and knees. Line up your head and neck with your back, and place your shoulders directly above your elbows. Tighten the abdominal muscles.
• Raise your right arm off the floor (top illustration). Hold for three deep breaths. Repeat with your left arm.
• Raise your right leg off the floor (bottom illustration). Hold for three deep breaths. Repeat with your left leg.
• For added challenge, raise your left arm and right leg at the same time. Repeat with your right arm and left leg.
