Arm Curls Crunch Left

Muscles worked: Biceps · Also: Abs & Core

Arm Curls Crunch Left combines a biceps curl with a crunch on the left side: you curl as you crunch, working the arm and the core in one coordinated move.

Coordinate the two halves — curl as you crunch, lower as you release — and keep the movement smooth rather than jerky. Use a light effort level; the value here is coordination and control, not heavy loading.

How to do it

1. Lie on your back with your knees bent and your arms ready to curl.
2. Curl as you crunch, lifting your shoulders a short way off the floor.
3. Coordinate the two halves — curl as you crunch, lower as you release.
4. Keep the movement smooth rather than jerky.
5. Use a light effort level; the value here is coordination and control, not heavy loading.
