Phase 2: Intensification

Strength Training
for Maximum Force

Transition from building size to expressing power. Optimize your neural drive with heavy loads.

The Strength Protocol

  • Intensity Zone: 80% - 90% of 1RM
  • Rep Range: 3 - 5 Reps
  • Rest Periods: 3 - 5 Minutes
  • Primary Driver: Neural Adaptation & Motor Unit Recruitment

Neural Adaptation vs. Hypertrophy

While hypertrophy training builds the "engine" (muscle size), strength training tunes the "software" (central nervous system). At intensities above 85% 1RM, your body learns to:

  1. Recruit High-Threshold Motor Units: These are the fast-twitch fibers capable of generating the most force.
  2. Rate Coding: Send signals from the brain to the muscle faster.
  3. Inter-muscular Coordination: Coordinate multiple muscle groups to fire synchronously.

The Specificity of Heavy Lifting

To get better at lifting heavy weights, you must lift heavy weights. A common mistake is staying in the "comfortable" 10-rep range for too long.Strength is a skill that needs to be practiced at relevant intensities.

Typical Strength Block Structure

This phase usually follows a hypertrophy block. The volume (total reps) decreases, but the intensity (weight on bar) increases significantly.

Common Questions

How long should I rest between sets?

For strength training, rest periods of 3-5 minutes are optimal. You need your ATP-PC energy system to fully replenish (which takes about 3 mins) so you can exert maximum force on every set.

Will I lose muscle mass if I only do low reps?

Not necessarily. As long as the volume is sufficient and the intensity is high, you can maintain muscle mass. However, strength blocks are usually shorter (4-8 weeks) compared to hypertrophy blocks to prevent burnout.
