Is the Correlation Between Hypertrophy and Strength Gains Stronger Than We Realized?

Greg Nuckols analyzes a Marques et al. study suggesting that the correlation between hypertrophy and strength gains may be stronger than prior research indicated, because earlier studies relied on between-participant statistics that obscured within-individual relationships. He clarifies that while hypertrophy likely contributes more to strength than previously thought, the apparent correlation is inflated by methodology, and early strength gains in untrained lifters still come largely from motor learning and technique.

Teaching:
• Frame early Ashtanga progress for beginners as motor learning and nervous system patterning, not physical change, so students stop measuring themselves by visible adaptations
• When advanced students plateau, point them toward tissue-level development (strength endurance, capacity) rather than chasing more technique refinement
• Use this to cue Navasana, Bhujapidasana, and arm balances: in early practice, leverage and breath organization matter more than raw strength
• Reinforce that individual anatomy (moment arms, insertions) explains why two students with similar shapes have wildly different capacities in the same pose

Idea map:
• Systems literacy: distinguishing within-individual signal from population averages parallels how practice rewards self-comparison over peer-comparison
• Embodiment: hypertrophy and strength as coupled but distinct adaptations echoes his framing of mobility, stability, and skill as separable practice variables
• Attention as method: the article models how the right measurement lens reveals relationships that crude metrics hide, mirroring how careful practice surfaces interior data
• Practice as method: training status changes which inputs matter most, supporting his ongoing argument that the same Ashtanga sequence is a different tool at different stages
