If you’re looking to add a little more variety to your core workouts, you can’t go wrong with the bicycle crunch. It’s a mainstay of ab exercises for good reason: It packs a major punch for all your abdominal muscles, particularly the obliques which often aren’t as engaged when you do traditional crunches. 

Read on to learn more about the bicycle crunch and how to do it, plus ways to make it easier or harder. 

What Is a Bicycle Crunch?

The bicycle crunch is a great exercise to challenge your core, especially your obliques, in a rotational pattern. The bicycle crunch is performed similarly to a standard crunch, but involves moving your legs in a cycling-like motion while twisting your upper body to each side. This extra rotation is what allows you to activate and strengthen your oblique muscles more than you’re able to when you simply crunch forward. 

What Muscles Do Bicycle Crunches Work? 

Similar to a standard crunch, the bicycle crunch works your entire core with a special focus on these muscles:

• Obliques, which run along the sides of the torso. These are the primary muscles engaged during a bicycle crunch. Bicycle crunches activate both the internal and external obliques, which help to stabilize the spine and pelvis. They also help you rotate your body in everyday activities.  

• Rectus abdominis, commonly known as the "six-pack" muscle. This is the major abdominal muscle that’s responsible for flexing the lumbar spine (low back) and it helps to stabilize the core when doing a bicycle crunch. 

• Transverse abdominis, which is located deep within the abdomen. It wraps around the spine to provide stability and acts a bit like a corset, tightening and stabilizing the core. The pedaling motion of the bicycle crunch allows you to tap into this set of deep core muscles.

Benefits of Bicycle Crunches

The bicycle crunch is a great, no-weights-needed exercise that challenges your core, especially your obliques, and builds strength for activities like carrying heavy objects, doing yard work, or lifting kids off the ground. You can also infuse a little cardio into this exercise by picking up the tempo, which can help build endurance. And, like all core exercises, the bicycle crunch can help alleviate back pain by helping to stabilize the core.

To do bicycle crunches:

• Start by lying on your back on a yoga mat. 

• Lift your head and shoulders off the mat, place your hands on the back of your head, and lift your legs to a tabletop position. 

• Now twist from the waist to bring one armpit and your opposite knee toward each other, extending the other leg long. 

• Return to center, then switch sides.

• Try to keep your elbows wide, and lift from your abdominals rather than pulling from your head.

As you do each rep, you might feel your core, back, and hip muscles working.

Everyone is different, which is why you may need to modify this exercise to meet your needs. 

To make bicycle crunches easier:  

• Keep your feet flat on the floor and your knees bent. Then lift your head and shoulders, and twist from side to side.

To make bicycle crunches harder: 

• Try a cross-body mountain climber by beginning in a high plank. Bend one knee to bring it toward your opposite elbow, and then return to plank.
