If your goals are to feel athletic, build a little size and strength, then bad ass is for you.
If you get training ADD and need to do extra workouts etc then WS4SB is better off.
It’s a fun program and the changing workouts are great however some people don’t like that you choose either a squat OR a deadlift.
When I did it, I alternated the squat and the deadlift each week and tbh it worked quite well. But like most people with an attaboy attitude I found myself looking for other workouts.
If you do it, and I do recommend it, then commit to it and don’t stray.
Think of it as you only have three chances a week to empty your fucking tank, so make every second in the gym count!
