Muscle gain: supplements and training volume
Hypertrophy is a function of volume, proximity to failure and load progression. Priority: total weekly volume per muscle group and an increase in working weights.
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 | 10–20 |
| Back | 12–22 |
| Shoulders | 8–18 |
| Biceps | 8–16 |
| Triceps | 8–16 |
| Quadriceps | 10–20 |
| Hamstrings | 8–18 |
| Glutes | 6–14 |
| Calves | 8–16 |
| Abs and core | 4–12 |
2–3 times per week per muscle group
60–85 % of 1RM
6–15 (equivalent at equal effort)
0–3 repetitions in reserve
90–180 seconds; for multi-joint compound exercises — up to 3 minutes
Add sets or weight when the top of the set range has been completed at the target RIR for two consecutive weeks.
Cardio
2 sessions per week, 3 minutes per week. low-intensity cardio for heart health and recovery
High-volume cardio on the same day as heavy legs impairs adaptation; separate them across days or place it after the strength session.
Deloads
Every 6–10 weeks, one week with a volume 40–50 % lower.
Block: 8 weeks, progression step 5 %. Deload on week 8 with volume 45 % lower.
Limitations
- More volume is not always better: past a certain threshold, fatigue and time increase, not results.
- If volume is growing but the weights on the bar have not moved for more than a month, the problem is in nutrition, sleep or the program, not in a lack of sets.
Supplements for this goal · 39
The level shows the strength of evidence, not importance: A means confirmed by reviews and meta-analyses, B means individual good randomised trials, C means data are scarce.
| Supplement | Level | Dose by goal |
|---|---|---|
| Creatine monohydrate The most studied supplement: a consistent moderate improvement in strength and muscle gain | A | 3–5 g per day daily; with resistance training about 1–2 kg of lean mass over 8–12 weeks |
| Curcumin Reduces creatine kinase and soreness after exercise; the effect is moderate | A | 500–1500 mg of curcuminoids per day |
| Whey protein Tops up daily protein; the source of protein matters less than its total amount | A | 20–40 g per serving, in total 1.6–2.2 g/kg/day |
| 'Testosterone boosters' (ZMA, tribulus and others) They do not increase testosterone in healthy men | B | There are no studies for this goal — no dose is invented. |
| Ashwagandha A modest effect on strength; the studies are small and heterogeneous | B | There are no studies for this goal — no dose is invented. |
| Betaine A small and unstable effect on strength; it changes body composition little | B | 2.5 g per day |
| Valerian One quality RCT showed improvement in sleep; there are no direct data on muscle and strength | B | There are no studies for this goal — no dose is invented. |
| Vitamin C (ascorbic acid) Corrects the deficiency but gives no gain in endurance; high doses interfere with adaptation | B | 200–500 mg per day |
| Vitamin D Useful only in deficiency: it does not increase strength in those with adequate intake | B | 1000–2000 IU per day to maintain the level |
| Weight gainer It is maltodextrin and sugar at the price of protein; ordinary food gives the same | B | There are no studies for this goal — no dose is invented. |
| Beef protein In a meta-analysis of seven RCTs it was not inferior to whey in lean mass and leg strength | B | 20–40 g per serving, in total 1.6–2.2 g/kg/day |
| Pea protein Was not inferior to whey in a 12-week RCT; less leucine per gram than in milk proteins | B | 25 g twice a day (50 g/day) is the studied dose; a reference point of 0.3 g/kg per serving |
| Casein protein A slow protein; an advantage over whey is not proven | B | 25–40 g per serving within a total protein intake of 1.6–2.2 g/kg/day |
| Leucine A separate supplement confers no advantage when protein is adequate | B | 2.5–5 g per day as a separate supplement or 0.025–0.05 g per kg of body mass; distribute protein at 0.4 g/kg per serving (4 servings) |
| Essential amino acids (EAA) Theoretically better than BCAA, but not better than a complete protein | B | 6–15 g per serving, providing 2–3 g of leucine |
| Plant protein blends Blends of pea and rice are close to whey; single-component ones are weaker | B | 25–40 g per serving; a 2:1 blend of pea and rice isolate, in total 1.6–2.2 g/kg/day (10–20 % more in a plant-based diet) |
| Soy protein A complete protein: in a meta-analysis of nine studies it was not inferior to animal proteins | B | 20–40 g per serving (20–25 g in the meta-analysis), in total 1.6–2.2 g/kg/day |
| Zinc Deficiency reduces strength and testosterone; with adequate status there is no effect | B | 15–25 mg of elemental zinc per day |
| Citrulline malate A modest effect: an increase in the number of repetitions is possible, the data are heterogeneous | B | There are no studies for this goal — no dose is invented. |
| BCAA (branched-chain amino acids) A weak effect: a complete protein does the same better and cheaper | B | 5–10 g at a leucine:isoleucine:valine ratio of about 2:1:1 |
| HMB (beta-hydroxy-beta-methylbutyrate) Almost useless for trained individuals: the evidence is contradictory | B | 3 g per day, divided into servings |
| Arginine Works poorly orally; the effect is weaker than that of citrulline | C | There are no studies for this goal — no dose is invented. |
| Astaxanthin The data are few and point in different directions; there is no convincing effect | C | There are no studies for this goal — no dose is invented. |
| Boron The data on testosterone and strength are weak and contradictory; the effect is not proven | C | There are no studies for this goal — no dose is invented. |
| Vitamin A (retinol, carotenoids) There are no sports data; excess is dangerous — chronic overdose is toxic | C | There are no studies for this goal — no dose is invented. |
| Glycine There are no data on sports performance; it has been studied mainly as a sleep aid | C | There are no studies for this goal — no dose is invented. |
| Coenzyme Q10 (ubiquinone) Raises the blood concentration, improves performance inconsistently | C | There are no studies for this goal — no dose is invented. |
| Creatine nitrate There are very few data; no advantages over monohydrate have been shown | C | 3–5 g per day as a source of creatine |
| Creatine HCl No proven advantages over monohydrate; overpayment | C | 3–5 g per day — for creatine as a whole. Choosing HCl specifically confers no advantages |
| Laxogenin A steroidal saponin from Smilax: there are no controlled data in humans | C | There are no studies for this goal — no dose is invented. |
| Methylsulfonylmethane (MSM) A single RCT showed no protection of muscle after exercise; data are scarce | C | There are no studies for this goal — no dose is invented. |
| Fenugreek Four RCTs out of six showed an effect, but the samples are small and the quality is low | C | about 500 mg/day of standardized extract, 8 weeks |
| Deer antler velvet The only RCT did not confirm a gain in strength or aerobic capacity | C | There are no studies for this goal — no dose is invented. |
| Oral ATP A meta-analysis of small studies; the quality of the data is low, the effect is unclear | C | There are no studies for this goal — no dose is invented. |
| Rice protein A hypoallergenic plant protein, but there are few direct comparative studies | C | 25–40 g per serving (a larger serving than for whey) |
| Tryptophan Does not increase performance; the sports data are old and weak | C | There are no studies for this goal — no dose is invented. |
| Turkesterone There are no controlled studies in humans; the popularity is not supported by data | C | There are no studies for this goal — no dose is invented. |
| Ecdysterone One small RCT showed muscle gain, but the effect is weak and has not been reproduced | C | there is no single dose: in the only RCT several different doses of the products were tested |
