|Utility:||Basic or Auxiliary|
Stand with hands on hips or in front of body.
Lunge forward with first leg. Land on heel, then forefoot. Lower body by flexing knee and hip of front leg until knee of rear leg is almost in contact with floor. Return to original standing position by forcibly extending hip and knee of forward leg. Repeat by alternating lunge with opposite leg.
Keep torso upright during lunge; flexible hip flexors are important. Lead knee should point same direction as foot throughout lunge. A long lunge emphasizes Gluteus Maximus; short lunge emphasizes Quadriceps.
Weighted versions of this exercise would normally be considered auxiliary in context of other basic exercises (ie: Barbell Squat, Sled Leg Press). However, in the context of 'body weight' only program, this exercise can be considered basic.
For less intensity, perform Split Squat.
Exercise can be made more challenging with additional weight. Also consider Step-ups.
