The other day, just to experiment, I tried BB "lunges", only I didn't step into the lunge, but rather placed my feet where they would be in a lunge, and then lowering my body until my rear knee touches the floor (gently), and my front knee is bent just past 90 degrees. I repped out a 5x5 working up to about 65% of my standard squat working weight (since only one leg is doing most of the work). I tried single leg BB squat with the rear foot elevated on a bench, but was a bit shaky. 2 days later, I'm still feeling it. I could tell this takes a bit of training of the stabilizers, which is a good thing. I've been crossfitting and training more for function/strength as opposed to appearance, so I'm moving in that direction.
1. Would my exercise be called a single leg squat or a lunge, since I didn't really step into the lunge? (I guess it doesn't matter what I call it, just curious)
2. Would progressing in this exercise still have the endocrine-boosting effect of regular full squats (assuming same intensity)?
3. Is there any reason why I couldn't substitute this exercise for regular squats and progress on it instead? I'm thinking the training of core, abductors, adductors, calf stabilizers, etc. is a bonus.
