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 groupSets per week
Chest8–14
Back10–16
Shoulders6–12
Biceps4–8
Triceps6–10
Quadriceps8–16
Hamstrings6–12
Glutes6–12
Calves4–10
Abs and core4–10
Frequency per muscle group

2–4 times per week per muscle group for compound movements

Load

80–95 % of 1RM

Repetitions

1–6

Reserve to failure

1–3 repetitions in reserve (not to failure)

Rest between sets

3–5 minutes between heavy sets

Progression

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.

Supplements for this goal · 53

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.

SupplementLevelDose by goal
Beta-alanine
Helps during exercise lasting 0.5–10 minutes; does not affect sprints shorter than 30 seconds
AThere are no studies for this goal — no dose is invented.
Sodium bicarbonate (baking soda)
Works for exercise lasting 1–10 minutes; the price is gastrointestinal upset
A0.2–0.3 g/kg 60–180 minutes before exercise, in divided doses
Caffeine
A working supplement: endurance +2–4%, strength moderately
A3–6 mg/kg 45–60 minutes before exercise
Caffeine in chewing gum
Fast and reliable action: the effect begins already on chewing
A200–300 mg 5–15 minutes before a set or before the start of resistance training
Creatine monohydrate
The most studied supplement: a consistent moderate improvement in strength and muscle gain
A3–5 g per day daily, including rest days; a loading phase of 20 g/day for 5–7 days accelerates saturation, but is not mandatory
Whey protein
Tops up daily protein; the source of protein matters less than its total amount
A20–40 g per serving within 1.6–2.2 g/kg/day
'Testosterone boosters' (ZMA, tribulus and others)
They do not increase testosterone in healthy men
BThere are no studies for this goal — no dose is invented.
Ashwagandha
A modest effect on strength; the studies are small and heterogeneous
B300–600 mg of standardized root extract per day, course of 8–12 weeks
Betaine
A small and unstable effect on strength; it changes body composition little
B2.5 g per day in a course of 2 weeks to 6 months
Valerian
One quality RCT showed improvement in sleep; there are no direct data on muscle and strength
BThere are no studies for this goal — no dose is invented.
Vitamin B12 (cobalamin)
Critical in a vegan diet; in athletes with adequate intake there is no effect
BThere are no studies for this goal — no dose is invented.
Vitamin D
Useful only in deficiency: it does not increase strength in those with adequate intake
B1000–2000 IU per day; strength increases only with initially low 25(OH)D
Glucosamine and chondroitin
In knee pain the effect is small and borderline significant; it does not restore cartilage
B1500 mg of glucosamine sulfate and 800–1200 mg of chondroitin per day
Beef protein
In a meta-analysis of seven RCTs it was not inferior to whey in lean mass and leg strength
B20–40 g per serving; in the meta-analysis a gain in lower-limb muscle strength was noted versus the absence of the supplement
Pea protein
Was not inferior to whey in a 12-week RCT; less leucine per gram than in milk proteins
B20–40 g per serving at a total protein intake of 1.6–2.2 g/kg/day
Calcium
Needed for bones, but supplements above the diet do not strengthen bones
B500–1000 mg per day as a supplement
Collagen peptides
A small effect on tendon pain; it does not change the structure
B15 g of hydrolyzed collagen or gelatin with 50–500 mg of vitamin C 30–60 minutes before loading of the tendons, course of 8–12 weeks
Maltodextrin
A cheap source of carbohydrate for prolonged work; produced no effect in resistance training
B2 g/kg 30–60 minutes before resistance training is the studied dose, without a gain in performance
Plant protein blends
Blends of pea and rice are close to whey; single-component ones are weaker
B25–40 g per serving at a total protein intake of 1.6–2.2 g/kg/day
Rhodiola rosea
The most consistently studied adaptogen, but the study results diverge
B1500–2400 mg/day for 4–30 days are the doses at which an effect was noted in strength tests
Soy protein
A complete protein: in a meta-analysis of nine studies it was not inferior to animal proteins
B20–40 g per serving
Taurine
The data are weak and heterogeneous; benefit is possible at high training volumes
B1–2 g 60–90 minutes before exercise
Tyrosine
Works under stress and sleep deprivation; in a calm state there is no effect
BThere are no studies for this goal — no dose is invented.
Zinc
Deficiency reduces strength and testosterone; with adequate status there is no effect
BThere are no studies for this goal — no dose is invented.
Sodium citrate
Alkalinizing supplement: a moderate effect on endurance, studied less thoroughly than bicarbonate
BThere are no studies for this goal — no dose is invented.
Citrulline malate
A modest effect: an increase in the number of repetitions is possible, the data are heterogeneous
B6–8 g 40–60 minutes before exercise; 8 g is more common in studies
L-theanine
Not ergogenic by itself; with caffeine it improves attention and reduces nervousness
