One of the most repeated recommendations in this sub is the suggestion to lift more. The suggestion to lift more is stacked in almost every advice given.

Just take a few moments to think. Think why most athletes, including those participating in fighting sports do NOT have immerse amounts of muscles... It's because too much muscle is excess muscle. It's not meant to be there. It's consuming to maintain after building it and it will lead to more body fat if for some reason you do not exercise enough. Your stamina is gonna take a hit if you go too far.

Learn to lift while taking your body type in account. Do not overdo it, do not under-do it either.

In short, just lift.
