The supine bicycle is a classic ab exercise. It has been around forever primarily because it is so effective. With a few simple movements, you can work your entire core, from abs to obliques.

 Muscles used in the supine bicycle

The supine bicycle is a great ab exercise because it uses so many core muscles at once.  Your lower abdominal muscles help keep your legs up and moving. Your upper abdominal muscles engage when you curl your upper body off the ground. Finally, your obliques help with the twisting motion as you reach your elbow over to touch your knee.

There aren’t too many ways to scale down the difficulty of this exercise. One method is to rest your extended leg on the ground rather that keeping it raised. The bottom line is that if this exercise is giving you trouble, you need to build up a base of core and abdominal strength.

Besides strapping on ankle weights, the best way to these make bicycles harder is to slow your speed way down. Each time your elbow and knee meet, hold that pose for a long moment. The isometric tension will smoke quickly your abs.
