Being sore doesn’t mean that muscle is being built, that’s a misconception, it’s actually muscle being damaged.

Soreness is actually micro-lesions in your muscles, and what builds them stronger is actually the rest following a workout. Because that’s when the body goes around to repair these lesions and builds stronger bonds within the muscle.

What builds muscle is resistance, nutrition and rest, the latter two being the most important.

You can’t build muscle if you don’t feed them right and give them time to recover.

So, killing yourself at the gym 3/4 days in a row, focusing on the same muscle group is actually really counterproductive.
Rotate your training focus with a split like push/pull/legs/core, or upper body/lower body/cardio, or whatever, as long as you enjoy it.

Give yourself time, eat right (as right as you can, don’t fall into the rice/chicken at every meal madness, balance is key), sleep a lot, take some rest days and deload weeks once in a while, and drink plenty of water. It’s a marathon, not a sprint.
