Lie flat on your back with your knees bent and heels close to your glutes, feet flat on the ground.

Place your hands behind your head with your elbows pointing outwards.

3

Dig your heels hard into the ground and isometrically contract your hamstrings and glutes before you begin curling up, keeping them contracted throughout the set.

Engaging your abs while maintaining the hamstring contraction, slowly lift your upper body off the ground, curling forward until your torso is at a 45-degree angle.

5

Pause for a moment at the top, then slowly lower your upper body back down to the starting position while continuing to dig your heels in and keep your hamstrings engaged.
