Training multiple muscle groups of the torso together on the same day can contribute to balanced strength, joint integrity, and overall health.

“I believe there's a clear benefit to training all these muscle groups together on the same day, because much in the same way that training legs all on one day can lead to these systemic effects because they're large muscle groups, working both the pushing muscles and the pulling muscles of the torso on one day, at least in the context of this program, is very time efficient, and tends to wick out into a number of different dimensions of health that at least I'm interested in and I think a lot of other people are interested in.”
