One-arm pull-up progression

Loop band on bar; foot in band; pull with one arm, band reduces the load.

Muscles

Primary
lats
Supporting
biceps, mid back

Mechanics

Pattern
vertical pull
Equipment
bodyweight
Geometry
150° Pull Pivot
Energy model
Glycolytic Pathway (10-90s)
Target feel
Extreme lat recruitment — assistance fades out as band resistance drops.
Progression
Thinner band; band only at bodyweight; full one-arm pull-up.
Regression
Archer pull-up or standard weighted pull-up as strength base.

Watch for

  • Too much band assistance — neural demand drops, adaptation stalls
  • Leaning away from bar instead of pulling bar to chest
  • Neglecting the slow eccentric

Substitutions

  • Archer pull-up
  • Pull-up weighted
  • Lat pulldown single-arm
