Muscle hypertrophy requires mechanical tension, metabolic stress, and muscle damage; tension is the primary driver.

Satellite cells donate nuclei to muscle fibers; nuclear addition supports long-term hypertrophy and is largely irreversible.

Myofibrillar protein synthesis peaks 24–48 hours post-training; rates stay elevated up to 72 hours in trained individuals.

Type I fibers: slow-twitch, fatigue-resistant, oxidative; Type II: fast-twitch, glycolytic, high force, fatigable.

Muscle fiber type shifts with training: endurance increases oxidative capacity; resistance training increases IIa proportion.

Body composition change rule: a 500 kcal daily deficit yields ~0.45 kg fat loss per week; surplus of 300–500 kcal supports lean gain.

Protein turnover: muscle protein breakdown exceeds synthesis in fasted state; net balance becomes positive with amino acids plus resistance exercise.

Rate of gain: novice can gain 0.9–1.4 kg lean mass/month; intermediate 0.45–0.9 kg; advanced 0.2–0.45 kg.

Hypertrophy load range: 60–80% 1RM for 6–12 reps; strength: 85–95% 1RM for 1–5 reps.

Effective volume: 10–20 hard sets per muscle group per week; diminishing returns above ~20 sets.

Progressive overload variables: load, reps, sets, density, range of motion, tempo; increase one variable at a time.

Training to or near failure (0–3 RIR) maximizes motor unit recruitment and hypertrophy stimulus.

Exercise order: compound lifts first when strength is the goal; isolation can precede compound for weak points.

Rest intervals: 2–5 minutes for compound strength; 60–90 seconds for hypertrophy isolation work.

Eccentric phase: 2–4 seconds under control increases time under tension and mechanical stress.

Specificity: strength gains are joint-angle and velocity-specific; train the movement pattern you want to improve.

Linear periodization: volume decreases while intensity increases across mesocycles (e.g., 12-week block).

Undulating periodization: daily or weekly fluctuations in volume/intensity; effective for strength and hypertrophy.

Deload rule: reduce volume by 40–60% or intensity by 10–20% every 4–8 weeks or when performance stagnates.

Supercompensation: recovery 48–72 hours per muscle group before retraining; sleep 7–9 hours optimizes hormonal recovery.

Heart rate variability (HRV) and resting heart rate are practical readiness markers; track trends, not single days.

Overtraining signs: persistent fatigue, decreased performance, elevated resting HR, mood disturbance, sleep disruption.

Training split frequency: hitting each muscle 2x/week yields equal or greater hypertrophy than 1x/week at matched volume.

Autoregulation: adjust load based on daily readiness using RPE/RIR; RPE 8 = 2 RIR, RPE 9 = 1 RIR.

Protein intake: 1.6–2.2 g/kg body weight daily for hypertrophy; 2.3–3.1 g/kg during caloric deficit to preserve lean mass.

Caloric surplus for lean gain: 10–20% above maintenance (~300–500 kcal/day); deficit for fat loss: 15–25% below maintenance.

Carbohydrate: 3–5 g/kg/day for moderate training; 5–8 g/kg for high-volume; prioritize around training.

Fat: 0.5–1.5 g/kg/day; minimum 20% of calories to support hormone production.

Creatine monohydrate: 3–5 g/day; loading 20 g/day for 5–7 days saturates muscle stores faster.

Protein timing: 20–40 g high-quality protein every 3–4 hours; total daily intake matters more than timing.

Caffeine: 3–6 mg/kg 30–60 min pre-training improves strength and endurance; avoid within 6 hours of sleep.

Hydration: 30–40 ml/kg/day; add 500–750 ml per hour of training; 2% dehydration impairs performance.

Goal setting: SMART criteria (specific, measurable, achievable, relevant, time-bound) improve adherence and performance.

Process goals (e.g., attend 4 sessions/week) outperform outcome goals (e.g., lose 10 kg) for behavior change.

Self-efficacy: mastery experiences, vicarious modeling, verbal persuasion, and arousal regulation build confidence.

Intrinsic motivation (autonomy, competence, relatedness) sustains long-term training more than extrinsic rewards.

Implementation intentions: 'If X, then Y' plans double adherence rates compared with vague intentions.

Self-talk: instructional self-talk improves technique; motivational self-talk improves strength and endurance.

Habit formation: average 66 days to automaticity; consistency matters more than intensity early on.

Tracking: logging training and nutrition increases adherence by 20–30% via self-monitoring and feedback.

Program template: 3–6 training days/week; each muscle 2x/week; 10–20 sets/muscle/week; 6–12 reps hypertrophy.

Session structure: warm-up 5–10 min, compound lifts 3–5 sets, accessory 2–4 sets, isolation 2–3 sets, cool-down.

Exercise selection: 1–2 compound per major muscle, 1–2 accessory, 1 isolation; rotate every 4–8 weeks.

Progression model: double progression (increase reps to top of range, then add load) is simple and sustainable.

Aesthetic priorities: shoulders, upper back, and glutes for V-taper and shape; balanced development prevents injury.

Adherence rule: program must fit schedule (3–5 days), equipment, and recovery capacity; complexity reduces compliance.

Recovery integration: schedule at least 1–2 rest days/week; sleep and nutrition are part of the program.

Monitoring: reassess physique and performance every 4–6 weeks; adjust volume, load, or calories based on trend.
