Strength: supplements and training volume
Strength grows from intensity and specificity, not from maximal volume. Volume is maintenance-level; the main work is in heavy sets.
Weekly volume by muscle group
The weekly set range is a working orientation from research, not a norm: inside it volume is matched to recovery.
| Muscle group | Sets per week |
|---|---|
| Chest | 8–14 |
| Back | 10–16 |
| Shoulders | 6–12 |
| Biceps | 4–8 |
| Triceps | 6–10 |
| Quadriceps | 8–16 |
| Hamstrings | 6–12 |
| Glutes | 6–12 |
| Calves | 4–10 |
| Abs and core | 4–10 |
2–4 times per week per muscle group for compound movements
80–95 % of 1RM
1–6
1–3 repetitions in reserve (not to failure)
3–5 minutes between heavy sets
Linear or undulating periodization: an increase in weight while repetitions are maintained, then an increase in repetitions at the same weight.
Cardio
2 sessions per week, 3 minutes per week. low intensity; high-intensity intervals sit outside a strength specialisation block
Concurrent strength and endurance work reduces strength gains if the cardio is high-volume and high-intensity.
Deloads
Every 4–6 weeks, especially before an attempt at a new maximum.
Block: 8 weeks, progression step 5 %. Deload on week 4, 8 with volume 35 % lower.
Limitations
- Training to failure with heavy weights increases the risk of injury and provides no advantage in strength.
- High-intensity intervals in large volumes suppress strength gains — separate them across phases.
