Why it matters: Pumping iron (or just using
your own body weight for resistance) increases
bone density, boosts metabolism and makes
you more self-sufficient for daily tasks.
From a plank position with hands slightly wider
than your shoulders, lower your knees to the
floor. Lift your bellybutton toward your spine
and draw your lower ribs together. Keeping your knees, hips, shoulders and head in one
plane, bend your elbows out to the side and
reach your chest (not your chin) toward the floor.
Aim to bend your elbows 90 degrees before
pressing back up to the starting position.
Do as many as you can while maintaining
proper alignment and lowering with control.
How to tell you’re improving: The number
you can do increases. After you can do 20 on
your knees with proper form, straighten your
legs and do them off your toes.
