EVERYTHING WORKS (to a certain extent).
We know this for a fact. We see guys who do 30 sets getting big and strong and weve seen guys do 3 sets a get big and strong.
The trick is finding something that motivates you and makes you excited to go to the gym.
I did Dr. Scotts Fortitude for 2 years, loved it. Much more like Nippards way in. Basically full body 3x a week rotating different rep schemes and structures. Really enjoyed it. But after about 2 years, i got stuck and wasnt "excited" to go attack the gym anymore. Same thing with PPL.
You just have to find something you enjoy and train HARD and you're fine.
I think most of my program choices are driven by DAYS OFF if i'm being honest. I did the whole train 6-7 days a week thing and i just cant do it.
I feel tired and underrecovered. I also feel l need a day mentally away from the gym. Even if its just cardio, I need a day to reset my food. Training days require me to eat A LOT and have 2-3 of those per week fits my lifestyle and motivation much more. After 1 day away from the gym, im readdyyy to attack weights.
