LPPLU is the 5-day variant MuscleBuddy ships as its canonical split. It puts a quad-dominant Legs day at the start of the week, sandwiches Pull and Push around recovery, then splits the second wave into a posterior-chain Lower (RDLs, hip thrusts, hamstring curls) and a combined Upper. Every major muscle group is trained twice, once heavy and once with a hypertrophy bias.
Splitting "leg work" into Legs (quad-led) and Lower (posterior-led) lets you train both halves of the lower body with full intensity. Squatting heavy on Monday and RDLing heavy on Thursday is easier on knees and lower back than two near-identical leg days, and the differing movement patterns drive better stimulus on each.
Use double progression on the working sets: hit the top of the rep range with form before adding weight. Main compounds (squat, RDL, bench, OHP, pull-up) anchor each day at RPE 8, with isolation and machine work pushed to RPE 9 to bias hypertrophy.
The block runs four working weeks with no deload week written in. MuscleBuddy eases a week for you when your recovery scores trend down, and you can take a deload week yourself whenever you need one.
