Man of Honour
Whilst I quite enjoy picking things up and putting them down, having something to focus on makes a world of difference for me.
I mostly lift to keep a good level of strength as I'm knocking on a bit now at 52, but my main hobby is hard* enduro and I've never known anything so physically exhausting, I should stop falling off it really.
*Well, more tepid/meek enduro at my current ability
Yes it's helped me focus more. Going to the gym just to lift started to bore me and I didn't really put the effort in. I wasn't really progressing nor particularly wanting to do it. I mean my strength is still there but maybe 30% down which is still better than most.
However I need cardio for martial arts, and speed. Strength and conditioning will help regardless. I need to keep my weight in my weight class as it makes life easier too!
I'm also well into my 40s so I need to be mindful of injuries and recovery. 2 heavy gym sessions a week and 3 Martial arts sessions a week keeps me in good shape. I can't do much more because of recovery and time.
