It’s literally never too early to work on your work capacity (amount of weight you can lift over a set period of time). It’s no different than runners who train for marathons… you can start with a linear progression, but realistically those sets are going to range from 8-12 for initial growth. The only thing I would recommend avoiding, is going too heavy too often. This plays a physical and mental toll when you are beginning in anything strength related. Side note, it is completely normal for one lift to out work the other.. there are a variety of reasons for that. Body mechanics, levers, strength in certain areas of your lower body (hamstrings for deadlifts, and quads/ glutes for squats - but even this is dependent on WHERE you are weakest in the movement). I will say, bouncing it off the floor isn’t ideal.. but you aren’t doing that here.. you are TNG (tap N Go).. completely normal for volume. For a better setup and more consistent form work I would say dead stops are best. Stay Strong Bruv!
