| Set | Weight | Reps | Notes |
|---|---|---|---|
| Warm-up 1 | 45 lb (empty bar) | 5 | Bar sits on rear delts, hip drive out of hole |
| Working sets 1–5 | 60 lb | 5 each | 90-second rest if easy; 3 minutes if hard |
| Set | Weight | Reps | Notes |
|---|---|---|---|
| Warm-up 1 | 45 lb (empty bar) | 5 | Elbows just forward of bar, grip just outside shoulders |
| Working sets 1–5 | 50 lb | 5 each | 90-second rest if easy; 3 minutes if hard |
| Set | Weight | Reps | Notes |
|---|---|---|---|
| Warm-up 1 | 65 lb (bar + two 10 lb plates) | 5 | Minimum pull height — cannot deadlift empty bar from floor |
| Working set | 100 lb | 5 | Rest 3–5 minutes before this single working set |
| Stretch | Duration | Target |
|---|---|---|
| Standing hamstring stretch | 30 sec each leg | Hamstrings (loaded by squat + deadlift) |
| Standing quad stretch | 30 sec each leg | Quads (loaded by squat) |
| Hip flexor lunge stretch | 30 sec each side | Hip flexors (compressed under load) |
| Child's pose | 30–45 sec | Spinal decompression, lower back |
| Doorway chest/shoulder stretch | 30 sec each side | Anterior delts and chest after OHP |
| Cross-body shoulder stretch | 30 sec each arm | Posterior delt and rotator cuff |
| Cat-cow | 5 slow cycles | Spinal mobility |
| Level | Squat | OHP | Deadlift | Notes |
|---|---|---|---|---|
| Beginner | 45 lb (empty bar — form only) | 45 lb (empty bar) | 65 lb (bar + two 10s) | Focus entirely on the 5-step setup for each lift; do not add weight until the pattern is automatic |
| Intermediate | 60 lb (today's weight) | 50 lb (today's weight) | 100 lb (today's weight) | Execute all sets; add 5 lb next session if all reps completed with good form 1 |
| Advanced | 65–70+ lb | 55–60+ lb | 105–115+ lb | If you are already at these numbers, apply the deload rule on any lift where you've failed 3 consecutive sessions: drop 10%, work back up in 5 lb increments 1 |
| Lift | Current (Monday) | Wednesday projection |
