I had my second "induction" yesterday. I told the guy I just wanted to go through the exercises I was doing, so he took me through deadlift, rows, squat, OHP, bench and showed me how to barbell press as well.
It was really helpful actually. I'm not 100% sure I have the deadlift down but I'm feeling a little more confident. As I said before, I might do Romanian deadlifts for a while to give my hamstrings some exercise as they're pretty tight. Rows he said were fine, just keep my elbows tucked in. Squat I was going too low and bending more to give the appearance of squatting lower. In reality, I was just bending my back unnecessarily. OHP was absolutely fine. Bench was interesting. I haven't found it massively challenging yet and he said that I needed to get my shoulders flat on the bench and showed me how. It was as much effort to lift as it was to keep my shoulders flat. I was still able to lift the same weight so that was great.
So, very valuable overall. I can book in with him again for free if I need to, so that's good.
