Core Training Principles

The foundational science behind every effective training programme, regardless of goal, experience level, or compound use.

Progressive Overload
The cornerstone of all strength and hypertrophy gains. Systematically increase the demand placed on the body over time — through added load, volume, density, or reduced rest — to force continuous adaptation.
Specificity (SAID Principle)
Specific Adaptation to Imposed Demands. The body adapts precisely to the type of stress applied. Train for your goal — hypertrophy, strength, power, or endurance — with appropriate rep ranges, loads, and movement patterns.
Recovery & Supercompensation
Muscle growth occurs during recovery, not during training. The training stimulus creates micro-damage; adequate rest, nutrition, and sleep allow the body to rebuild stronger — the supercompensation window.
Volume & Frequency
Training volume (sets × reps × load) is the primary driver of hypertrophy. Frequency determines how that volume is distributed across the week. Higher frequency with moderate volume per session outperforms low-frequency, high-volume approaches for most goals.
Beginner vs. Advanced Considerations

Beginners (0–2 years)

  • Full-body or upper/lower splits 3–4× per week
  • Master movement patterns before adding load
  • Linear progression works — add weight every session
  • 10–15 sets per muscle per week is sufficient
  • Compounds first: squat, deadlift, bench, row, press

Intermediate/Advanced (2+ years)

  • Push/pull/legs or body-part splits 4–6× per week
  • Periodisation required — linear progress has stalled
  • 16–22 sets per muscle per week for hypertrophy
  • Technique refinement and injury prevention critical
  • Structured deloads every 4–6 weeks are non-negotiable

Challenging the Broad Endorsement of Zone 2 Training for Mitochondrial Capacity in the General Population

A review challenges the widespread recommendation of Zone 2 training as optimal for mitochondrial capacity in the general public, suggesting it may be overhyped compared to high-intensity exercise for non-athletes.
