| Protocol | Sets | Starting % | Reps per set | Best for |
|---|---|---|---|---|
| Standard | 4 | 40% | 8, 5, 3, 1 | General training, hypertrophy-oriented |
| Starting Strength | 5 | 40% | 5, 3, 2, 1, 1 | Novice linear progression programs |
| Competition | 6 | 50% | 5, 3, 2, 1, 1, 1 | Meet day, 1RM testing, max-effort singles |

Standard Protocol (4 Sets)
The most widely used warmup sequence for strength and hypertrophy training. Starts at 40% with moderate reps and steps down as weight increases.
| Set | % of Working Weight | Reps | Purpose |
|---|---|---|---|
| 1 | 40% | 8 | Blood flow, groove the pattern with light load |
| 2 | 60% | 5 | Temperature increase, light neural activation |
| 3 | 75% | 3 | Sub-maximal neural prime, technique confirmation |
| 4 | 90% | 1 | Near-working load, CNS activation without fatigue |
| Working sets | 100% | as programmed | Main effort |
Worked example — 225 lb bench press:
| Set | Weight | Reps | Plates (per side, 45 lb bar) |
|---|---|---|---|
| 1 | 90 lb | 8 | 1×25 + 1×10 lb |
| 2 | 135 lb | 5 | 1×45 lb |
| 3 | 170 lb | 3 | 1×45 + 1×25 lb |
| 4 | 202 lb | 1 | 1×45 + 1×35 + 1×2.5 lb |
| Working | 225 lb | × sets | 2×45 lb |
When to use: Any training day where you have multiple working sets (3×5, 4×6, 5×3, etc.). The moderate reps at the lower end build adequate warmth without producing fatigue before the main work.
Starting Strength Protocol (5 Sets)
Derived from Mark Rippetoe’s Starting Strength program. Uses one more set with a final heavier single compared to the Standard protocol. Favors low rep counts throughout to minimize fatigue accumulation.
| Set | % of Working Weight | Reps | Purpose |
|---|---|---|---|
| 1 | 40% | 5 | Pattern rehearsal, core temperature |
| 2 | 60% | 3 | Progressive loading |
| 3 | 80% | 2 | Sub-maximal activation |
| 4 | 90% | 1 | Heavy single, neural prime |
| 5 | 95% | 1 | Very close to working weight |
| Working sets | 100% | 3×5 | Main effort |
Design principle: The SS protocol prioritizes keeping rep counts low to prevent meaningful fatigue accumulation before the 3×5 work sets. At 95%, the jump to 100% is only 5% — the nervous system barely notices the transition.
When to use: Primarily on SS, GSLP, or similar 3×5 linear progression programs where the working sets ARE the primary stimulus. The extra set at 95% is especially helpful once working weights are heavy enough that the jump from 90% to 100% would otherwise feel sharp.
Note: For very light working weights (under ~135 lb / 60 kg), the SS protocol may over-warm — the Standard protocol is adequate and involves less total work.
Competition Protocol (6 Sets)
Used on meet day, during 1RM testing, or on max-effort training days. Starts at 50% (not 40%) because the lifter is already thermally prepared from earlier in the warmup room, and includes a true opener single at 100%.
| Set | % of Working Weight | Reps | Purpose |
|---|---|---|---|
| 1 | 50% | 5 | Initial activation (skip 40% — already warm) |
| 2 | 65% | 3 | Progressive ramp |
| 3 | 75% | 2 | Technique under moderate load |
| 4 | 85% | 1 | Heavy single |
| 5 | 90% | 1 | Near-opener single |
| 6 | 100% | 1 | Opener single (meet: timing-specific) |
| Competition attempt | opener | 1 | Platform / test |
Competition day timing: The 100% single (set 6) should finish 5–8 minutes before you step on the platform. For a 3-attempt meet, time your warmup so:
- Set 5 (90%) = ~15 minutes before your opener attempt
- Set 6 (100%) = ~8 minutes before your opener attempt
This ensures the neuromuscular system is fully primed without allowing post-activation potentiation (PAP) to dissipate.
Important: “Working weight” in this context means your planned opener attempt — not a training max. Build your warmup percentages from the opener, not from your true 1RM.
Protocol Selection Guide
| Situation | Use |
|---|---|
| First heavy exercise of training session | Standard or SS |
| Second exercise after related heavy lift (e.g., squat after deadlift day) | 1–2 warmup sets only |
| 1RM test or max-effort day | Competition protocol |
| Powerlifting meet, any lift | Competition protocol |
| Working weight under 135 lb / 60 kg | Standard (2–3 sets may suffice) |
| Working weight over 400 lb / 180 kg | SS or add a set at 85% to Standard |
Notes on Rep Count Logic
The key design principle across all protocols: rep count decreases as weight increases. This limits total volume and fatigue before the working sets while still achieving the warmup goals.
A common mistake is performing high reps (5–8) at 80–90% of working weight. At 80%, 5 reps is meaningful work — it accumulates neuromuscular fatigue and reduces performance on working sets. Keep sets at 80%+ to 1–3 reps.
A second common mistake is taking too many warmup sets at the same percentage (“I did 135 × 10, 135 × 8, 135 × 5…”). Repeated sets at the same weight do not advance the warmup and add unnecessary fatigue. Each set should increase weight.
Plate Loading Quick Reference
