Lower-Body Circuit, Exercise 2: Lateral Lunge to Curtsy Lunge
Stand tall with your feet shoulder-width apart. Take your right foot and step it out wide to the right side, shifting your bodyweight over your right leg while simultaneously lowering into a squat. Keep your left leg out straight.
Drive through the right foot to stand up, and step the right foot behind the left leg and toward the left as you lower down into a curtsy lunge.
Keep your torso upright and return back to standing by pushing through the left foot.
This counts as one rep. Perform for 30 seconds on each leg.
