Two largest muscle groups on the same day – don’t throw-up!
I don’t know of anything a fear more than legs and back on the same day. I personally love doing back because it is an area many people can see fast results (and it builds a number of other body parts at the same time), but doing legs with back is simply exhausting. This will be one of the toughest workouts no matter how many times you’ve done it. This is a fat-burning, heart-pumping, muscle-building routine that, if done right and with intensity, will leave you feeling sore every time.
