Tired of just doing normal step lunges? try this
variation which targets the hamstrings and glutes.
1. At smith machine, start in a lunge position with one foot on a
step or box and other leg in lunge position behind you.
Making sure your back is straight.
2. Push with the foot that's on the box while the lunged leg
is raised up to hip height. Doing this in a dynamic motion is
great for cardio as well as targeting the glutes.
