Great to have you on board Witten. There are so many options out there for a beginniner and ive been overwhelmed with information. At this moment i just want to stick a program and stick with it for a little bit. I will probably do Starting Strenght for a few months for now and when I start stalling on my lifts I will go on to another program.
I am terrified of Benching btw, I much prefer dumbel benching over barbell but I dont think that makes too much of a different.
Oh yeah btw, critique my squat form. 60k @ 85kg. Really bad but I am weak as fuck at the moment!
Yeah there will be nothing wrong with SS, it is a great program. As for weight gain, I do not know how skinny you are. Aim for a .5 kg/ 1 lbs a week for 1-2 months if you are super skinny. After the first month or two I would back it off to .25kg/ .5 lbs a week. If you would like to lose weight, I would just start out with a small deficit. You do not have to eat a ton or eat like shit to make good progress. After you stall on SS (could be over 6 months), I would recommend the Texas Method.
Your squat form looks actually pretty decent from what I can see. I would recommend some flat sole shoes to give you a more solid base; it looks like you are wearing running shoes. Make sure that you are trying to get really tight before you descend into the hole; I cannot really tell from the video, but I definitely recommend breathing in and bracing your core on every single lift you perform (not just for the squat).
Keep learning as much as you can, if you are interested in this type of stuff, and I will be happy to help you if I have time (which will probably only be on the weekends).
The reason that you should use a barbell as opposed to dumbbells is because it will be easier to get set up for a barbell bench press rather than a dumbbell. It is hard to stay tight getting the dumbbells in position, where as on the barbell bench press you can get set up before you unrack the weight, this will allow for more consistent progress because you can ensure you get set up the same way every time.
Take your time to learn the bench press technique. It took me over a year to get the technique down and I wasn't make consistent progress beforehand, so it definitely is worth the time. I recommend this video(or article), but it will probably take a lot of patience
Bench Press . You do not necessarily need an ultra wide grip, but the rest of the principals are good.
