Bicycles are one of the most effective abdominal exercises. It activates your side oblique muscles as you twist and your rectus abdominus, down the middle, as you transition from side to side. Be sure to stay lifted as you twist from side to side. Don’t roll from side to side. The goal is for both shoulders to be off the ground at all times.
