Sure no problem at all doing that. I personally like doing full body workouts so I do a leg exercise and an upper body pushing movement and upper body pulling movement. This is a little from both books in every workout. At your level I’d also recommend a core specific exercise. But just play around with programming and see what works best for you. I’d recommend a heavy pulling day and a heavy pushing day, something like this:
Day 1: pull ups, push ups, hanging L leg raise, lunges/split squats/etc.
Day 2: dips, Australian pull ups, plank/back bridge progression, tuck jump squats
Consider doing back bridges as part of a warm up or cool down because they’re exceptionally beneficial so it is a great habit to do them often in some form.
