Bicycle Crunch

Often times, simple google search for the best ab exercise won’t grant us the best results. Thankfully, an ACE sponsored study done at the Biomechanics Lab at Sand Diego State University came up with a list of the best and worst ab exercises ranked by muscle stimulation level.

Surprisingly enough, crunches after all are the best ab exercises above other popular ab workouts like planks. 

But traditional crunch just doesn’t cut it. It’s the Bicycle Crunch that you remember your mom used to do in the living room is what ranked the highest in the ab exercise ranking.

While Bicycle Crunch generated the muscle activity level of 248%,  Reverse crunch and traditional crunch just made it to about 100%.

Without further adieu, here is how to perform Bicycle Crunch in 3 easy steps.
