So a bit of a backstory: I found TRP around a half a year ago and it changed my mind completely. I joined a gym but only fucked around for the first 3 or 4 months, only now did I actually start a decent diet and so on, and TRP really helped me out A LOT already, but im still a virgin (due to my own approach anxiety issues since I had plenty of obvious opportunities).

Fastforward 2 months ago to now im starting to finally see some changed in my body and I love it! But I still have somewhat not-perfect posture and my flexibility is a big round zero. Also my joints are not the best for the average 20 year old since I spent the last 7~8 years sitting all day long playing video games and doing shit all.

(No backstory ->) So I come here to ask if any of you have any tips or plans I can apply each day or so to improve my flexibility and some warmup or post-workout plans to help the joints recover and so I dont cry everytime I get up from my bed 30 years from now.
