How necessary is it to have someone who knows what they are talking about to correct your form while learning to squat, deadlift, bench press etc?
I've always been put off from the gym because I hate machines. I was pretty excited when a friend showed me Starting Strength by Mark Rippetoe and I started researching him more. Turns out the best way to start off is to learn the standard compound lifts (squat, bench, deadlift, clean, overhead press) to build strength and don't use machines/do isolation exercises at all. This appeals to me far, far more. The problem is I'm kinda worried about learning how to do the movements. If I've learnt anything it's that form is so important that you simply cannot get it wrong or you risk hurting yourself and/or making less progress than you should. This is off putting because I only have videos and books to learn form from, nobody there to correct me on the fly.
Like, I'm just trying to learn to squat at the moment. Just a bodyweight squat. It's really hard, I can't do it properly without falling over backwards at the minute. I'm not even ready for the empty bar I don't think. It doesn't help that I have no sense of what my body is doing in the slightest. I can't tell if my lower back is rounded or not, or if my knees are pointed outwards enough at the bottom of the squat. Having never paid attention to these things, it's hard to know what it feels like to be in the right position. I think I might be too worried about form. but I want to get it right.
