I’m not reading the entire thread so I’m not sure if this has been said
but the two most important things IMO is being consistent with your exercise/workout ( doesn’t matter if you miss one day just get back into it the next day bcs at the end of the day all that’s important is that you are moving), and your diet. Eat like crap you’ll feel like crap.
These two things are how I went from an underweight scrawny guy To someone who looks normal. I’m not jacked in anyway or form but I do feel much better than I used to. Physically and mentally.
