Barbell bench press
The barbell bench press is one of the best-studied ways to build the chest and triceps, and the standard test of upper-body strength. Training trials in men and women show clear growth of the pectoralis major and triceps within 6–10 weeks. The shoulder is where it costs most, and grip width and shoulder-blade position change how much load the shoulder takes.
What the science says
- Builds the chest and triceps Strong evidence
In Ogasawara et al.'s 2013 trial, young men who bench pressed 3 sets of 10 at 75% of 1RM three times a week increased the cross-sectional area of the pectoralis major and triceps along with their 1RM; gains were fastest in the first 6 weeks and slowed afterward. Häkkinen et al. (2022) found pectoralis major thickness rose about 14–18% and bench press 1RM about 13–17% after 10 weeks of upper-body strength training in young women.
- Heavy loads for maximal strength, any load near failure for size Strong evidence
Schoenfeld et al.'s 2017 meta-analysis of 21 studies found that 1RM strength rose more with heavy loads (above 60% of 1RM), while muscle growth was similar across light and heavy loads when sets were taken to failure. For the bench press, that means heavy sets for a bigger 1RM and a wide rep range for chest growth.
- Grip width and shoulder blades change shoulder load Limited evidence
Noteboom et al. (2024) modelled 21 bench press variations in 10 experienced strength athletes: a grip narrower than about 1.5 times shoulder (bi-acromial) width reduced compression at the acromioclavicular joint, and both that grip and pulling the shoulder blades back reduced shear forces and rotator cuff demand at the shoulder. This is a computer model of joint loads, not an injury trial.
How to do it
Muscles trained: pectoralis major, anterior deltoid, triceps brachii
- Lie with your eyes under the bar, feet flat and planted
- Pull your shoulder blades back and down and keep them there for the whole set
- Grip a little wider than your shoulders (no more than about 1.5 times shoulder width), forearms vertical at the bottom
- Lower the bar under control to the lower chest, elbows angled in rather than flared straight out
- Touch the chest without bouncing and press up and slightly back over the shoulders
- Use safety arms or a spotter when you train close to failure
How to apply it
Use it as your main chest press, 1–3 times a week, stopping most sets 1–3 reps short of failure.
Who should be careful
The shoulder takes the most strain in pressing; keep the shoulder blades set, avoid very wide grips and add load gradually. Never take sets to failure alone without safety arms or a spotter. Pain at the front of the shoulder that persists across sessions is a reason to stop pressing and see a physician or physical therapist.
Frequently asked questions
Do I need heavy weights to grow my chest with the bench press?
No. Schoenfeld et al.'s meta-analysis found similar muscle growth with light and heavy loads when sets were taken to failure. Heavy loads matter for maximal strength: they raised 1RM more.
How should I program the bench press?
For size, 3–4 sets of 6–12 reps stopped 1–3 reps short of failure; for strength, 3–5 sets of 3–6 reps at about 75–90% of 1RM. Rest 2–3 minutes (3–5 for heavy sets) and bench 1–3 times a week.
Which grip is easiest on the shoulders?
In Noteboom et al.'s model, a grip narrower than about 1.5 times shoulder width and shoulder blades pulled back reduced shoulder joint loads. It is a biomechanical model, not a trial that counted injuries.

More exercises
- Back squat Strong evidence
The barbell back squat reliably builds the quadriceps, glutes and adductors and is one of the best-studied lower-body exercises in training research.
- Front squat Moderate evidence
The front squat holds the bar on the front of the shoulders, which keeps the torso more upright and loads the knees less than the back squat while recruiting the thigh muscles about as much.
- Bulgarian split squat Moderate evidence
The Bulgarian (rear-foot-elevated) split squat trains one leg at a time and builds the quads and glutes with far less load on the bar than a back squat.
- Leg press Strong evidence
The leg press builds the quadriceps about as well as free-weight squats and also grows the glutes and adductor magnus, with no balance or spinal-loading limit.
- Hack squat (machine) Moderate evidence
The machine hack squat lets you squat deep on a fixed track with your back supported, which makes it easy to push the quads close to failure.
- Romanian deadlift Moderate evidence
The Romanian deadlift is a hip hinge that loads the hamstrings and glutes at long muscle lengths, and trials of stiff-leg deadlifts and similar hip-extension exercises show real hamstring growth, mainly in the semimembranosus and biceps femoris long head.
