How to do the Chin-Up

Steps

1. Grab the pull-up bar with the palms facing your torso and a grip closer than the shoulder width.
2. As you have both arms extended in front of you holding the bar at the chosen grip width, keep your torso as straight as possible while creating a curvature on your lower back and sticking your chest out. This is your starting position. Tip: Keeping the torso as straight as possible maximizes biceps stimulation while minimizing back involvement.
3. As you breathe out, pull your torso up until your head is around the level of the pull-up bar. Concentrate on using the biceps muscles in order to perform the movement. Keep the elbows close to your body. Tip: The upper torso should remain stationary as it moves through space and only the arms should move. The forearms should do no other work other than hold the bar.
4. After a second of squeezing the biceps in the contracted position, slowly lower your torso back to the starting position; when your arms are fully extended. Breathe in as you perform this portion of the movement.
5. Repeat this motion for the prescribed amount of repetitions.

Tracking it in OneRep

Add the chin-up to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.

Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.

Where the instructions come from

The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
