Assisted Close-grip Underhand Chin-up

Assisted Close-grip Underhand Chin-up

The Assisted Close-grip Underhand Chin-up is a challenging upper body exercise that primarily targets the muscles of the back, specifically the lats and biceps. It is a variation of the traditional chin-up, with a narrower hand position and an underhand grip on the bar. The close grip engages the muscles in a slightly different way, placing more emphasis on the biceps and lower lats. This exercise requires a pull-up bar or a Smith machine with an adjustable bar height. To perform the Assisted Close-grip Underhand Chin-up, you'll need a resistance band or an assisted pull-up machine to provide assistance if needed. By utilizing this equipment, individuals who may struggle with full bodyweight chin-ups can still benefit from the exercise. The Assisted Close-grip Underhand Chin-up offers several benefits. It effectively strengthens the upper back muscles, helping to improve posture and upper body pulling strength. The biceps are also engaged, promoting arm muscle development and grip strength. Additionally, this exercise engages the core muscles as stabilizers, contributing to overall core strength and stability. Incorporating the Assisted Close-grip Underhand Chin-up into your workout routine can be an excellent way to challenge your upper body and build strength. However, it is important to ensure proper form and technique to maximize its benefits. Subtle adjustments in grip width and hand placement can target different muscle groups, so experiment to find what works best for you. As with any exercise, gradually increase intensity and resistance over time to avoid overexertion and prevent injury.


  • Stand facing a high bar that is set between waist and chest height.
  • Grasp the bar with an underhand grip, hands shoulder-width apart.
  • Place your knees or feet on a stable surface (bench or chair) to assist with the movement.
  • Keep your core engaged, shoulders down, and chest lifted.
  • Initiate the movement by pulling your body up towards the bar. Focus on using your back muscles and arms, avoiding excessive swinging or using momentum.
  • Continue pulling until your chin is above the bar.
  • Pause briefly at the top of the movement, squeezing your back muscles.
  • Lower your body in a controlled manner until your arms are fully extended, but make sure to maintain tension in your back muscles throughout the entire range of motion.
  • Repeat for the desired number of repetitions.
  • Remember to breathe properly throughout the exercise.
