| Heavy compound pairs (Bench+Row, OHP+Pulldown, Squat+Calf, BSS+Calf) | 90 sec after pair |
| Medium/isolation pairs (Press+Fly, Hip Thrust+Leg Curl, Curls, Triceps) | 60 sec after pair |
| Deadlift — straight sets only | 2–3 min between sets |
| Walking Lunges — straight sets only | 2 min between sets |
| Between superset groups (A→B→C) | Move straight to next group |
Coleman & Schoenfeld et al. (2024): Supersets = same hypertrophy, strength, and body composition in 36% less time. Schoenfeld (2017): 10+ weekly sets/muscle optimal for hypertrophy. Grgic & Schoenfeld (2019): Training each muscle 2×/week superior to 1×/week. Ethier & Trexler (2024): 5-day ULPPL scores highest among all splits for hypertrophy.

| Heavy compound pairs (Bench+Row, OHP+Pullup, Deadlift+BSS) | 90 sec after pair |
| Medium/isolation pairs (Press+Fly, Leg Curl+Leg Ext, Curls+Lateral) | 60 sec after pair |
| Barbell Squat and Deadlift — straight sets | 2–3 min between sets |
Ethier & Trexler (2024): 4-Day Upper/Lower hypertrophy score = 8.4, top among 4-day splits. Each muscle trained 2× per week — optimal frequency. Volume graph from Pelland et al. meta-analysis shows higher volume = more growth. Coleman & Schoenfeld (2024): Supersets = same gains in 36% less time.
| Main compound (Squat, Deadlift) — straight sets | 2–3 min between sets |
| Heavy compound superset pairs (Bench+Pullup, OHP+Row) | 90 sec after pair |
| Accessory superset pairs (BSS+Face Pull, Fly+Hip Thrust, Curls+Pushdowns) | 60 sec after pair |
Ethier & Trexler (2024): 3-Day Full Body hypertrophy score = 8.1. Training each muscle 3× per week gives a small but real frequency advantage. Pelland et al. meta-analysis: training muscles 3×/week can boost strength gains by ~50% vs 1×/week, same volume. Best option for busy schedules — 3 sessions, all muscles hit every session.
