Performing the: A Step-by-Step Tutorial 45 degree one leg hyperextension
Secure your feet firmly under the foot pads, with one foot released and extended straight behind you, keeping your other foot firmly anchored.
With your hands either across your chest or behind your head, and your back straight, bend forward slowly at the waist as far as you can while keeping your other leg extended.
Once you've reached the maximum extension, start raising your upper body while keeping your back straight, and squeeze your glutes at the top of the movement.
Repeat this motion for the desired number of repetitions, then switch legs and repeat the process.
