5 Exercises for Strong, Gorgeous Abs -- No Crunches Necessary
This isn't just a vanity thing. Your abs are the main support system for your spine and the place where almost all movement in your body is initiated. With these easy core exercises, you have no more excuses for weak abs
This looks simple but is by far the best exercise to strengthen your abs! Lie on the floor face down and lift your body so you are supported on your forearms and toes. (If you need to modify this exercise, keep your knees on the ground.) Make sure that your shoulders, hips, and knees stay in one straight line. Elbows should be directly below shoulders. Hold the plank for 15-60 seconds. When you are able to hold the plank for 60 seconds without much effort, you can add challenges by lifting one foot slightly of the ground, placing your elbows on a stability ball or holding the pose on your hands and toes.
