During pull ups, your latissimi dorsi is the primary mover and your triceps are the main stabilizer muscle. As for your stabilizer complexes, they are all functioning depending on which joint is involved in the movement.
Which muscles are the prime movers stabilizers and synergists in a pull up?
According to Frederic Delavier, author of “Strength Training Anatomy,” several synergistic muscles in the arm and back are used to carry out a pull-up, though only the latissimus dorsi and the teres major are the primary movers.
What is the antagonist muscle in a pull up?
The supraspinatus is a pullup antagonist, because it is also responsible for abducting your shoulders, which is the opposite movement that occurs during pullups.
What muscles are used in a pullup?
One of the reasons the wide-grip pullup is such an incredible exercise is because of the many muscles used to perform the move:
- Latissimus dorsi. …
- Trapezius. …
- Thoracic erector spinae. …
- Rhomboids. …
- Infraspinatus. …
- Teres minor. …
- External oblique.
Is a pull up concentric or eccentric?
An example of concentric contraction would be the upward pull during a pull up. Eccentric contractions occur when the muscles lengthen while generating force. An example of eccentric contraction would be lowering down from the top of a pull up (AKA the negative).
What muscle is the prime mover in a pull up?
Muscles Worked During a Pull-Up
Your latissimus dorsi is the most powerful pulling muscle in your back, and during a pull-up, it’s the primary mover, or the muscle that provides most of the power to bring your body up to the bar.
What are the agonist muscles in a push up?
So the agonist muscles for a push-up are the pectoralis major, biceps (shoulder flexion), triceps (elbow extension), and serratus anterior, pec minor (scapular protraction). They are working concentrically during the up phase, and then eccentrically during the down phase—they are the agonists for both phases!
What are the synergist muscles for bench press?
In the bench press, the prime movers and synergists (agonists) are: the anterior deltoids, the triceps, and the pectorals/serratus.
What are the antagonist muscles in a walking lunge?
The hamstrings are the agonist and the quadriceps are the antagonist.
What is the antagonist in a lunge?
Antagonist – Pectoralis major. Squat Muscles and Walking Lunge. Agonist – Gluteus maximus, quadriceps. Synergist – Hamstring complex. Stabilizer – Transverse abdominus.
Are pullups or Chinups better?
Most of the time, chinups will be recommended before pullups. If your workout routine is already strenuous on your biceps or your lower back, pullups may be the better option. On the other hand, chinups would be good for people whose training program is already pulling too much in the upper back.
Does pull-ups work chest?
What muscles do pull-ups work? Pull-ups target your back muscles primarily, specifically your lats, but also your chest and shoulder muscles.
Why are wide grip pull-ups so hard?
The wider your grip, the less help your lats get from other muscles, making a rep harder.
What is an example of a concentric contraction?
Contractions that permit the muscle to shorten are referred to as concentric contractions. An example of a concentric contraction in the raising of a weight during a bicep curl. In concentric contractions, the force generated by the muscle is always less than the muscle’s maximum (Po).
What are the benefits of eccentric training?
Check out these five body-rocking benefits of eccentric training:
- Faster muscle gains. Rep per rep, eccentric training is superior to concentric training at building both muscle size and strength, research shows. …
- Greater metabolic boosts. …
- More flexibility. …
- Lower risk of injury. …
- Better sports performance.

How do you do eccentric pull-ups?
Eccentric Pull-Up Set-up: Start with both hand on the pull-up bar. Squeeze your glutes and tighten your abs. Jump your chin over the bar. Execution: Descend under control.
