Yeah, I’ve been doing strength training 2 hours 3x/week with a coach, and I would never attempt this without a coach.

Every work set she’s watching me and making frequent adjustments. It would be impossible for me to do this without her. Maybe I could record video and analyze it, but I would have to essentially learn all of her expertise and even then it would be delayed so I couldn’t make fixes until after I have already completed a dangerous set.

At the very least I would recommend a good two months or so during your linear progression. After that you can do volume sets, pause sets etc alone, with coaching maybe twice a month for heavy days and to check in on your form.
