31 yr old male working sets for chest are 25 kg .... 12......11..... 10reps, what should be ideal warm up sets ie weight and no of sets, or are warm up srts required here?
This is a fitness/training question, not a medical one, so I'll answer directly from exercise science principles.
Warm-Up Sets for 25 kg Working Sets (Chest)
Yes, warm-up sets are worthwhile even at this load. They prime the neuromuscular system, grease the movement pattern, and reduce injury risk — especially for shoulder-heavy pushing movements.
Recommended Warm-Up Protocol
| Set | Weight | Reps | Purpose |
|---|---|---|---|
| 1 | Bar only / 10 kg | 15 | Movement pattern, shoulder prep |
| 2 | 15 kg | 10 | Gradual load introduction |
| 3 | 20 kg | 6 | Approach working load, low fatigue |
Then go into your working sets at 25 kg.
Key Principles Applied
- 3 warm-up sets is sufficient at this load — you don't need 5+ sets like a powerlifter handling 150 kg
- Keep reps moderate-to-low on the last warm-up set (5–6 reps) so you don't accumulate fatigue before the working sets
- Don't skip the bar/light set — rotator cuff and shoulder capsule need gradual loading regardless of total weight
- The jump from 20 kg → 25 kg (your working weight) is small enough to not need an intermediate set
Are Warm-Up Sets Required Here?
Technically no, but practically yes — especially for:
- Pressing movements (shoulder joint is vulnerable)
- If you're training early morning or after a sedentary workday
- If you notice strength/rep drop-off early in Set 1
If you've done a 10-minute general warm-up (cardio/dynamic stretching) beforehand, you could potentially reduce to 2 warm-up sets (10 kg × 12, then 20 kg × 6).
Your Rep Pattern (25/12, 11, 10)
This is a solid hypertrophy pattern — progressive fatigue across sets with rep drops of 1–2. You're likely close to failure by Set 3, which is appropriate for muscle growth. No changes needed there.
Each set said above is rir 1 to 2
Good detail. RIR 1–2 (1–2 reps left in the tank) across all three sets confirms you're training at the right intensity for hypertrophy — genuinely hard but not grinding failures.
What This Tells Us
With 25 kg at RIR 1–2 giving you 12 / 11 / 10 reps:
- Your true max at 25 kg is roughly 13–14 reps on a fresh set
- You're accumulating fatigue well across sets (dropping 1 rep per set is textbook)
- This is solid volume overload territory for chest hypertrophy
Warm-Up Recommendation Stays the Same — But With One Tweak
Since your working sets are genuinely demanding (not just moderate effort), warm-ups matter more, not less. Cold muscles at RIR 1–2 = higher injury risk.
| Set | Weight | Reps | RIR |
|---|---|---|---|
| 1 | 10 kg | 12–15 | Easy, ~RIR 8+ |
| 2 | 17.5–20 kg | 6–8 | Moderate, ~RIR 5–6 |
| 3 | 22.5 kg | 3–4 | Close to working load, ~RIR 4 |
- Set 3 at 22.5 kg for just 3–4 reps activates the load without costing you reps on your working sets
- Rest 90–120 sec after the last warm-up before starting Set 1
Progressive Overload Pointer
At RIR 1–2 consistently hitting 12 / 11 / 10, you're ready to progress when:
- All 3 sets hit the top of your rep target (e.g. if your goal range is 10–12, hit 12/12/12)
- Then add 2.5 kg and expect a drop to roughly 10 / 9 / 8 — that's normal and correct
You're training this well already.
What should be rest time between warm up sets
Rest Between Warm-Up Sets
Keep it short — 60 seconds or less.
| Transition | Rest |
|---|---|
| Set 1 → Set 2 (10 kg → 20 kg) | 45–60 sec |
| Set 2 → Set 3 (20 kg → 22.5 kg) | 45–60 sec |
| Set 3 → Working Set 1 (22.5 kg → 25 kg) | 90–120 sec |
Why Short Rest for Warm-Ups?
- Warm-up sets are sub-maximal — you're not creating meaningful fatigue, so you don't need full recovery
- The goal is to stay warm and primed, not to fully recover between each
- Long rests between warm-ups defeat the purpose — muscles cool down and the nervous system disengages
Why Longer Rest Before Working Set 1?
- The final warm-up set at 22.5 kg, even for 3–4 reps, activates heavier motor units
- You want those fully recovered before your first hard set
- 90–120 sec bridges the warm-up and working phases cleanly
Total Warm-Up Time
~5–6 minutes from first warm-up set to first working set. That's efficient — enough to be ready, not so long that you lose warmth or waste time.
