One-Arm Pull-Up Negative

A controlled, slow lowering from a one-arm hold, building toward the demanding full one-arm pull-up.

Setup

Start at the top of a pull-up, using a box or assistance to get there. Grip the bar with one hand, the other hand free or lightly assisting.

Movement

Lower yourself as slowly as possible using only the working arm. Resist the descent with maximum control, taking as long as your strength allows. Use the assisting hand only as needed. The goal is to minimize assistance over time as strength improves.

Return

Repeat for multiple controlled negatives. Quality of the slow descent matters more than the number of reps.

Common Mistake to Avoid

Attempting this before substantial pull-up and chin-up strength is built. This is an advanced progression requiring a very strong foundation in standard and weighted pull-ups first.

Equipment Pull-up bar
Primary Muscles Biceps, back (latissimus dorsi)
Secondary Muscles Forearms (grip)

Why it matters

Lowering yourself slowly from the top of a pull-up using only one arm trains the eccentric (lowering) strength needed for a full one-arm pull-up, which is an extraordinarily demanding goal requiring exceptional relative strength. This negative-only version is the standard, sensible progression toward that long-term goal.

How to do it

  1. Start at the top of a pull-up, using a box or assistance to get there. Grip the bar with one hand, the other hand free or lightly assisting.
  2. Lower yourself as slowly as possible using only the working arm. Resist the descent with maximum control, taking as long as your strength allows.
  3. Use the assisting hand only as needed. The goal is to minimize assistance over time as strength improves.
  4. Repeat for multiple controlled negatives. Quality of the slow descent matters more than the number of reps.

Common mistakes

  • Attempting this before substantial pull-up and chin-up strength is built. This is an advanced progression requiring a very strong foundation in standard and weighted pull-ups first.
  • Dropping quickly instead of controlling the descent. A fast drop defeats the entire purpose — the slow, controlled lowering is what builds the needed strength.
  • Relying too heavily on the assisting hand. Gradually reduce assistance over time as the working arm's strength improves.
  • Treating the full one-arm pull-up as a near-term goal for most trainees. This is one of the most demanding bodyweight feats and represents a multi-year journey for most people who pursue it — appropriate patience matters.

Sets & reps by level

Beginner

Not applicable — build substantial pull-up and chin-up strength first.

Intermediate

Not typically attempted yet — continue building two-arm pulling strength.

Advanced

3–4 sets of 3–5 slow negatives per arm once a strong two-arm pulling foundation is established.
