I've weighted trained for a long time now, although I have found this year, I've dropped down to just going to the gym 4 times a week (previously 5 days). My training style has changed a bit in the last 6 months as well. I used to focus a lot on the "big 3" bench press, squats and deadlifts, but I'm finding that less interesting than I used to.
I've been following Jeff Nippard's Essentials programme for the last 4 weeks (
https://jeffnippard.com/products/the-essentials-program) doing 4-day split. Upper Lower, Upper Lower. It's designed to be completed in about 45 mins max. And as I go to the gym during my lunch, I've found I'm rushing less to try and get to the gym and back within an hour with previous routines.
I've started playing golf in the last 6 months, as my mates have all decided that as they're too old for football and wanted to do something else. My walking has increased a lot since taking it up, so I'm finding it a happy balance of doing weightlifting still but getting outside and doing some cardio. Albeit less at the moment with the weather and weekdays being dark by 4pm ish. Not sure I've seen anyone mention golf on here before, but assume it will not be acceptable
With diet, I've found what works for me is trying to work out what my calories would need to be to stay at the same weight, then reduce that by 250-400 calories (depending on my goals) and then adjust as needs be. You will need to find what works for you but try not to make it too complicated. I'll always recommend MyFitnessPal to get you tracking though. More often than not, you're just eating more than you think you are. Everything really adds up.
