>Muscle starts burning badly while in the gym >What is

those are called pumps brainiac

Lactic acid build up. I only get it when I'm going high reps. At higher weight and lower reps, my muscles get tired before the burning kicks in. I've never had the burning last for 10 minutes, though. Maybe a minute or so.

What about calf pumps? Long duration uphill walks feel good but the calf hurts so fucking badly

I hear its because the sugar in the body is being burned up and thats why it hurts

Lactic acid build up, get some beta-alanine to deal with it.
