I always thought Sumo Squats were wide leg squats but you do them with legs shoulder width. Any particular reason?
This was intended to really stress the point of wider knees during the squat. I called them Sumo Squats, but really they could've (and should've) been called goblet squats. I was trying to stress a more natural squat form similar to a front squat, for example, using a barbell.
I think you referred to bent over rows as "reverse pushups" in the video. I had always understood reverse pushups to be a bodyweight exercise where you use a dipping bar or a bar bell on a rack, hang face up from it, and pull yourself up to the bar. You can vary the angle of your body by moving the bar up and down or by bending your knees more or less to vary the intensity.
Yup, the pull action you are referring to is actually very similar to the barbell row. The reason I refer to it as a "reverse push-up" is because of the plane the arms travel through their range of motion. I used dumbbells in this workout, although it is intended to be done with a barbell. I actually prefer this variety versus the one you refer to by pulling your body weight towards a bar because the standing variety recruits far more muscle in the glutes, hamstrings, and lower back (not to mention the mid and upper back!)
