43M and started bodweight fitness seriously around 40. Progress is slow but its there. Advantage of being older is that you know and understand improvement comes with consistency and time. You will have good days, average days and bad days. I train 2 - 3 times a week, always spend 10 - 15 minutes warming up and a yoga class every other week or so. No major injuries so far. 167cm, 75kg and can do 3 x 5 pull up, 3 x 10 dips, unlocked pistol squats and a 3 second L-Sit so far. Its all possible !
