I haven't lifted in 5-6 months and i just started a job at a pottery warehouse unloading heavy ass pottery and cast iron shit from trucks. The morning after my first day I was sore as hell so i took a hot/cold contrast shower and i felt fucking amazing afterwards. The soreness was still there that day but i felt so good i started doing it everytime i shower now. I never really did it right before because i was too much of a puss for the cold water but it's so worth it. I'm addicted now.
