Step-by-step instructions
Follow these cues to master proper technique and stay safe through every rep.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Step 7Repeat
- Repeat the pull-up and lower-down motion for the desired number of repetitions.
