Like Muskate said, it's will vary alot person to person.
By their Training Discipline (BB-er or Powerlifter).
I know when I Power-lifted, I usually went On 2, Off 1, On 2, Off 2.
If not I really got Burnt-out.
But now that I switched to more of a BB-er style.
I pretty much do what Muskate does, I do a Push-Pull Super-set on 3 days, then I'm off from Lifting 1 Day, and then repeat.
But I'll do Abs, and some Bodyweight work if I think it's needed.
If not, it's Abs and Cardio, and the Cardio can vary widely, from Hiit with Battle Ropes, Heavy Bag, Wind Sprints.
I can't really just sit around on my day off from lifting while On-Cycle.
But I do keep it Short and Intense for Abs and Cardio.............................................. JP
P.S.
You really need to Track your Workouts, to see how you're doing.
There's No 1 Correct way, as we are All Individuals, and respond differently to Stimuli.
