Partner-assisted Chin-up
The Partner-assisted Chin-up primarily works the Latissimus Dorsi, with secondary activation of the Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), Trapezius (Middle) and stabilizer support from the Biceps Brachii (Long Head), Triceps (Long Head). It is a none compound exercise at beginner difficulty.
The Partner-assisted Chin-up is a beginner compound exercise, following a vertical pull movement pattern. It primarily targets the Latissimus Dorsi, with secondary engagement of the Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), Trapezius (Middle). This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Latissimus Dorsi is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), and Trapezius (Middle) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Biceps Brachii (Long Head), Triceps (Long Head) act as stabilizers, maintaining joint position and postural alignment throughout the movement.

How to Perform
Preparation
- Step up and grasp bar with underhand shoulder width grip.
- Bend knees so partner can assist from behind.
Execution
- Pull body up until elbows are to sides or chin is just above bar.
- Lower body until arms and shoulders are fully extended.
- Repeat.
Comments
- Partner can assist as needed by pulling ankles or top feet up from behind.
- Also seeself-assistedtechnique.
Tips & Common Mistakes
- Initiate by pulling your shoulder blades down before bending your elbows.
- Avoid swinging or using momentum — control every inch of the range of motion.
- Full range of motion matters: start from a dead hang for maximum lat stretch.
Programming Suggestions
Adapt your sets and reps to your training goal. As a beginner-friendly exercise, start with lighter loads and focus on form before progressing weight.
| Strength | 3–5 sets × 3–6 reps at 80–90% 1RM with 2–4 minutes rest. |
|---|---|
| Hypertrophy | 3–5 sets × 6–12 reps at 65–80% 1RM with 60–120 seconds rest. |
| Endurance | 2–4 sets × 15–20 reps at 50–65% 1RM with 30–60 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Latissimus Dorsi) and can be substituted based on your equipment or variation preferences.
