So it’s push pull legs on a 4 way rotation. Chest shoulders tri/back width, back thickness, bicep, forearms/calves, hams, quads.
Rest pause is failure, 15 breaths, failure, 15 breaths, failure. Back thickness, quads, calves, and forearms are not rest paused. Reps depends on exercise. For chest I like to fail somewhere in the 8-12ish range fir the first one. For something like biceps it would be more like 14/7/4. You only do 3 rounds. When your able to do more reps than you total number you up the weight. So maybe for chest that total number is 20. If I get 10/5/2 I’ll go for more reps next workout. But if I managed 13/6/4 I would add weight.
