Walking lunge

Dumbbells at the sides, torso tall, step long enough that the front heel stays down.

Walking lunge
  1. 1Lower the back knee toward the floor.
  2. 2Keep the front knee over the mid-foot, not caving in.
  3. 3Push through the front heel to stand and step through.

Easy to miss: A short step that dumps the knee and folds the torso forward.

Muscles

Copper on the figure is a prime mover. The softer tone helps.
