PPL alternates push, pull, and leg sessions so each major movement pattern gets a full rest day before being trained again. With six sessions a week you hit every muscle group twice — the well-established weekly frequency for maximizing hypertrophy.
The two-wave structure (Heavy → Volume) lets you push close-to-1RM intensity on day one of each pattern, then chase pump and metabolic stress on the second wave with higher reps, more isolation, and shorter rest. Top working sets sit at RPE 8 on heavy days and RPE 9 on volume days.
On MuscleBuddy this program runs with double progression by default: stay in the rep range, hit every rep with good form, and the next session adds a small weight increment. When you stall two sessions in a row, the engine drops volume and re-tests to break through the plateau.
Mesocycles run four hard weeks plus one deload (~60% volume). Treat the deload as productive — it lets accumulated fatigue dissipate so the next block opens with a new strength baseline.
