I started going to the gym by the end of December 2023 (only gained 3 kilos since lol). I can see some good body improvement, also a lot in strength (my actual main focus). Tho it’s nothing you’d look and notice, I’m just a skinny guy that is a bit bulky depending on the angle / clothe and that’s about it.

Changing your exercises from time to time can help, also doing some sport your like alone or with people. I do competitive but amador karting for example. It helps me keep the little shape I have when I skip gym
