Execution

Warm-up

  • 1 × 8 @ 60% PL
  • 1 × 8 @ 70% PL

Main Work

  • Recruitment (low volume): 1–2 × 5 @ 80% PL
  • Complete all prescribed sets without failure.

Execution

Warm-up

  • 1 × 8 @ 60% PL
  • 1 × 8 @ 70% PL

Main Work

  • Recruitment (low volume): 1 × 5 @ 80% PL
  • Strength Cycle Progression: 5–10 × 5 @ 80% PL
  • Complete all prescribed sets without failure.

Technical Focus

Focus on precise and repeatable force production:

  • Apply smooth, controlled force without spikes
  • Keep output consistent across all reps
  • Avoid compensatory tension in shoulders and body
  • Maintain stable grip position and engagement
  • Prioritize quality over total volume

When to use it

Use when strength is the primary quality of the session.

  • Standalone strength session
  • Pre-climb recruitment (low volume)

12-Week Progression Model

Organized into three 4-week waves.
Volume increases across blocks while intensity remains fixed at ~80% PL.

Block 1 (Weeks 1–4): Volume Foundation
Increase total sets (5–7).
Focus: Stable force production at prescribed intensity.

Block 2 (Weeks 5–8): Load Consolidation
Maintain moderate–high volume (7–8 sets).
Focus: Consistent output at ~80% PL without fatigue spillover.

Block 3 (Weeks 9–12): Recruitment Emphasis
Increase volume toward upper range (8–10 sets).
Focus: Maximal high-threshold recruitment while preserving movement quality.

After Week 12
Re-test PL and recalculate working loads if Peak Load increased.

Frequency

  • 1–2 × per week during strength phases
  • Perform as a standalone session or first component of the session
  • Avoid placing after high-fatigue work

Expected Effects

Over time:

  • Increased maximal finger force (Peak Load)
  • Improved high-threshold motor unit recruitment
  • Better force maintenance across repeated contractions
  • Stronger transfer of finger strength to climbing performance
