Starting out: when should you move up a size on weights?
Edit: I am 32, UK based. Currently on a weight loss diet with high protein low carb intake.
I have 0 upper body strength so I am currently lifting a measly 2.5kg in each arm. Started out three weeks ago with one weight session a week (no PT, just YouTube guides and workouts)
I tried moving to 5KG today, and it felt okay for a bit, but I had serious burning and couldn't keep control of my reps.
I know I am early into it, but just wanting to know guidence so I can try and plan ahead. I worry I may stick to the easy stuff too long and still struggle.
