I’ve lifted pretty seriously in the past, though always under guidance, so something like rippetoe might be too long winded on exercise explanations, but from a progress perspective I’m closer to a beginner— aside from having previously developed some of the neural pathways. 5/3/1 was my go-to in younger days but now I’m older and looking for more general fitness and athleticism as opposed to size/strength specific.

I’ve been using gambetta’s athletic development and it’s been great for circuit training and overall increase of work capacity but I’m finding that when it comes to programming it sort of falls flat in that recommendations are very generic. I would like something that would educate me on the whys and let me come away with the ability to design my own programs depending on situational needs. Any recs would be appreciated
