The only thing I can do is run
Every time I walk into the gym I tell myself "this is gonna be the day you start lifting bro" but then everything looks like a medieval torture instrument and I fuck off to the treadmill
Hey Bro, I highly suggest watching youtuber and fitness bloke 'Calum von Moger', hes super chill and shows you correct form without showing off and being in your face about it. Watching him has corrected my form on so many excersises it isnt even funny.
Good luck bro, we are all going to make it.
P.S If you don't like Calums sense of humor and want a more serious approach to this then there are litterally MILLIONS of different websites, articles, or even youtubers dedicated to helping people like you out.
