Two of the most popular splits, head to head. Frequency, volume and recovery — and how to pick the one your schedule can actually sustain.
The honest answer is that both work, and the split you will actually run beats the one that looks better on paper.
Upper/lower hits each muscle roughly twice a week on four days. PPL gets you there too, but only if you run it six days. On three or four days, PPL drops to once-weekly frequency — which is where it starts losing ground.
PPL spreads volume thinner per session, which is easier to recover from and easier to finish. Upper/lower front-loads it; those sessions get long.
The split matters far less than the years you put into it.
Losing fat without losing muscle is a numbers game. Here is the exact deficit, the protein floor, and the refeed cadence we program for a cut that actually holds.
The one-gram-per-pound rule gets you close, but context changes everything. What the research says for cutting, maintaining, and building.
Motivation is weather; systems are climate. How a visible streak rewires the decision to show up until it stops being a decision at all.
