Description
The Bicycle Crunch is a dynamic abdominal exercise performed lying on your back with a pedaling motion, targeting both the lower abs and obliques. It involves an alternating cross-body movement where the right elbow meets the left knee, and the left elbow meets the right knee. The rectus abdominis (especially the lower fibers), obliques, and hip flexors are highly activated. Thanks to continuous rotation and hip flexion, it also elevates the heart rate, making it both a strength and cardio exercise. It offers a much more comprehensive abdominal workout compared to a classic crunch because it targets the entire core. Since it requires no equipment, it is practical for home, office, park, or travel environments. When performed regularly, it provides significant improvements in lower ab development, oblique definition, and core endurance.
