Crunch straight leg up

Muscles involved

Adding the crunch straight leg up into your routine brings clear physical results that you will feel both during and after your workouts. By keeping your legs lifted using only your body weight, you keep your abdomen under constant tension while flexing your upper spine toward your feet. The key benefit you will notice over time is a significantly stronger core section, which translates into better upright posture, less lower back discomfort, and enhanced core stiffness whenever you execute heavier compounds like squats or overhead presses in your weekly sessions.

How to do it

1. Lie on your back and lift your legs straight, forming 90 degrees with your torso. 2. Extend your arms forward. 3. Lift your upper back, bringing your hands towards your feet as you exhale. 4. Lower your torso controllably to the starting position as you inhale.
