Bicycle Crunch Exercise. One of the best ab exercises. Sports Medicine. The Bicycle Crunch is the best ab exercised according to research done to uncover the best exercises you can do to activate the rectus abdominus. A study done at San Diego State University compared thirteen common abdominal exercises in an effort to determine the best.
You will perform this exercise as a variation on ab crunches. The difference is that you always have both feet off the ground during these bicycle crunches. This makes bicycle crunches a bit harder, than standard ab crunches. Also, it tends to work the lower abs more. Typically, keeping your legs off the ground works the lower abs. Keeping your legs flat, on the other hand, works the middle abs. Interestingly, bicycle crunches also work the rectus abdominus muscle (upper abs). This is the highest set of ab muscles you have.
