Lift Lunge: Hamstrings, Glutes, Quadriceps, and Abdominals
Start standing on a hard floor with a slider or towel underneath your right foot, with your right leg extended behind you.
Bend your left knee as you lower into a lunge following a four-count tempo. Keep your torso upright, and keep your left knee over your ankle at all times.
Repeat the same four-count tempo as you straighten your left leg and return to the starting position. This counts as one rep.
