Demonstration of Lunges

Yes I know he is using a barbell! But his technique for the actual lunge is terrific!! Note once he has stepped forward, his upper body moves down and up rather than back and forward. His knees both move to 90 degrees at the lowest point of his lunge and he stands UP before moving back into his starting position.
This is EXACTLY how I want you to perform your lunges. Have a look at the next video for a bit more information.
