Plank is a fairly simple but intense and effective isometric move that works your abdominal and back muscles. No equipment is needed for this exercise although a mat can be used for comfort. Using only bodyweight, planks can be a simple way to get a great core workout.Since planking engages more abdominal muscles than sit ups and crunches, it is more effective at building them. Having stronger abdominal muscles and more lean muscle mass increases metabolism and burns more fat. Other benefits besides building strong abdominal muscles that planking can improve are posture, balance, bone health, and flexibility.Next
