Yeah, Abe, I found it to hit my quads similar to a squat while stressing my lower back and erectors greatly due to having to keep your back very straight as the center of gravity is in front of you.
Next time I see Denny I’m going to walk up to him, hug him and lift him off the ground, shake him back and forth so that his feet will swing side-to-side and exclaim:
“Hey guys, is THIS how you do the Habecker?”
