Improve your health in 60-seconds!
If you have 60-seconds, you can improve your health. Just do a plank! Dr. Sherry Pagoto is a professor of medicine at the University of Massachusetts Medical School. She says planks target your abs and lower back, strengthening your core and making your spine more stable. That’ll help you avoid injuries and pain. If you can’t hold a plank for a minute at first, try 20 seconds and work your way up.
