Peterson Step Up

A step-by-step form guide from the Ægir Iron exercise library: how to do the lift, what to watch for, and the muscles it trains.

Equipment

Bodyweight

HOW TO PERFORM

1. Stand facing a low step and set the ball of one foot on it, heel raised and knee pushed forward over the toes.
2. Drive the heel down onto the step as you straighten the knee, lifting yourself until the working leg is locked out.
3. Let the free leg hang without pushing off the floor with it.
4. Reverse under control: bend the knee forward and rise back onto the ball of the foot as the free foot returns to the floor.
5. Finish the reps, then switch legs.

FORM TIPS

• Use a low step, around 15 cm. The range is short and the work is in the last part of straightening the knee.
• Lock the knee fully at the top of every rep.

TARGET MUSCLES

Primary

• Quads

Secondary

• Glutes
