Yeah, time is a killer.
You could have just done the squats like you said or you could have maybe supersetted the other stuff to save time. You know, what I mean, you speed up the little stuff to give the right attention to the big stuff.
The beauty of it is your not pushing weight you don't feel like pushing your just giving your body a better environment. At the same time...if it ain't happening, it ain't happening....
Don't like steak?
