Step-by-step instructions

Follow these cues to master proper technique and stay safe through every rep.

  1. Step 1Setup
    • Approach the assisted chin-up machine and adjust the knee pad to a comfortable height.
    • Ensure that the weight is set to a level that provides assistance for your body weight.
  2. Step 2Grab the Handles
    • Stand on the platform and grasp the handles with an underhand grip (palms facing you).
    • Position your hands shoulder-width apart for optimal grip.
  3. Step 3Position Your Body
    • Kneel on the knee pad, ensuring your knees are securely positioned under the pad.
    • Engage your core and keep your body straight, avoiding any excessive arching or leaning.
  4. Step 4Pull Up
    • Begin the movement by pulling your body upward, focusing on using your arms and back.
    • Keep your elbows close to your body as you pull yourself up towards the handles.
  5. Step 5Reach the Top
    • Continue pulling until your chin is above the handles, squeezing your shoulder blades together at the top.
    • Hold the position for a brief moment to maximize the contraction.
  6. Step 6Lower Down
    • Slowly lower your body back down to the starting position, fully extending your arms.
    • Maintain control throughout the descent to avoid dropping too quickly.
  7. Step 7Repeat
    • Repeat the pull-up and lower-down motion for the desired number of repetitions.
    • Focus on maintaining proper form throughout each rep.
  8. Step 8Finish the Exercise
    • After completing your reps, carefully step off the machine and adjust the knee pad back to its original position.
    • Take a moment to stretch your arms and back after the workout.
