Used to do weightlifting as a hobby back in my university days, and I even got some pretty good results, but then life happened.
I stopped training after graduating. I had no more time for it.
Nor did I have time for much of anything aside from work if I'm honest. It kept on for years, more than a decade, before it got better and I didn't need to work as much. I got worn down but kept at it.
Through it all I managed to keep a semblance of social/romantic life going and watched more than my fair share of Hockey, but physical training? Everything but the bare minimum got thrown out the window.
Until recently that is, with me on the cusp of semi-retiring.
Long story short, I thought I'd managed to keep myself in relatively good shape through the years by eating semi-healthy, lifting weights in my home gym, some jogging, and all. But that first training session with the trainer trying to slowly get back to that weightlifting form was a (very) rude awakening, to say nothing of the muscle pain I felt the day after.
Neverthless, I will keep at it and sooner rather than later I will go back to being a "buff boi".
