Sprinter Crunch
Description
The sprinter crunch is a dynamic core exercise where you lie on your back and explosively sit up while driving one knee toward the opposite elbow, mimicking a sprinting motion. It trains the rectus abdominis, obliques, and hip flexors simultaneously with a dynamic, athletic pattern.
Equipment Required
Sprinter Crunch Instructions
- Lie flat on your back with arms at your sides and legs extended straight.
- Brace your core. Press your lower back into the floor.
- Explosively sit up while simultaneously driving your right knee toward your chest and swinging your left arm forward (like a sprint).
- Your left elbow should approach your right knee. Your right arm swings back naturally.
- Pause briefly in the crunch position, then lower back to the flat starting position.
- On the next rep, drive your left knee and right arm forward.
- Continue alternating for the desired total reps.
- Move explosively but with control. Do not slam down on the descent.
