|Utility:||Basic or Auxiliary|
Stand with one foot on bench or elevated surface. Position foot on elevated surface to side and forward of straight knee.
Stand on bench by straightening leg and pushing body upward. Step down returning foot off of bench to floor and repeat. Continue with opposite position.
Keep torso upright during exercise. Knee of exercised leg should point same direction as foot. Exercise can also be performed by placing travelling foot onto and off of bench next to foot of exercised leg (See demo). Park bench, picnic table and other elevated surfaces can also be used instead of a bench. 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.
Besides assisting more with arm, shorter bench or step will make this movement easier.
For greater challenge, use taller bench or box, or do not utilize assistance from arm.
