FitnessTracker is a local-first, privacy-focused fitness application that helps you measure progress, track workouts, and stay consistent — all without subscriptions, logins, or tracking. This page covers how to perform the alternate heel touchers, including tips, variations, and the muscle groups it targets.
This simple crunch variation improves lateral core strength and coordination. It can be done anywhere and works especially well in high-rep ab circuits.
Instructions
- Lie on your back with knees bent and feet flat on the floor, slightly wider than hip width.
- Extend your arms toward your heels, palms facing down.
- Crunch your torso up and to the right, reaching toward your right heel.
- Return to center, then crunch to the left to touch your left heel.
- Continue alternating sides with control for the desired number of reps.
