As a trainer, people always ask me, “What’s the one exercise that I should do if I only have a few minutes to workout at home?” The answer is always the same, PLANK! It literally works every muscle in your body at once, even the heart. There are so many modifications to plank to make it appropriate and safe for all fitness levels. If you have bad wrists, go to forearms. If you are wanting to make it harder, alternate lifting one leg off the ground. Need more cardio, do a walking plank, which is alternating forearms to wrist back and forth for a full minute. If you want stronger shoulders, elevate your feet on a chair or BOSU ball. Add a push-up while holding plank. The list goes on and on. As long as your abs are firmly engaged to protect your low back muscles, much like a Reese’s, there’s no wrong way, to do a plank!
