The bench press is the classic upper-body strength builder — a horizontal push that trains the chest, front shoulders and triceps together. Here's how to do it with good form, the muscles it works, the mistakes to avoid, and how to program it.
The barbell bench press is a compound horizontal push that primarily works the chest (pectoralis major), with the front deltoids and triceps as major assisting muscles. You lie on a flat bench, lower the bar to your mid-chest with elbows tucked and shoulder blades pinned back, then press it back up to lockout. It's one of the most effective ways to build upper-body pressing strength and chest size, and it's easy to progress because you can add small increments of weight to the bar over time.
The bench press is a compound lift, so it trains several muscles at once. The chest does most of the work, assisted by the shoulders and triceps, while the upper back and legs stabilize you on the bench.
| Role | Muscles | What they do in the lift |
|---|---|---|
| Primary mover | Pectoralis major | Drives the bar away from the chest (horizontal push) |
| Assisting | Anterior deltoid | Helps press the bar up, especially off the chest |
| Assisting | Triceps brachii | Extends the elbows to lock the bar out at the top |
| Stabilizers | Upper back, forearms, legs | Keep the shoulders set and the body braced under load |
Step-by-step form for the flat barbell bench press. If you're new, start light and consider using a spotter or safety pins.
If you want to train the same pattern with a different emphasis or equipment, these are the common swaps:
The bench press fits almost any upper-body or push day. General starting points:
| Goal | Sets × reps | Notes |
|---|---|---|
| Strength | 3–5 × 3–6 | Heavier load, longer rest (2–3 min), leave a rep or two in reserve on most sets |
| Muscle size | 3–4 × 6–12 | Moderate load, controlled tempo, train close to failure on the last set |
| Frequency | 1–2× / week | Progress by adding a little weight or a rep when you hit the top of the range |

Log every bench set — weight, reps, and an RPE value — in LiftHero, and it charts your progressive overload and flags personal records so you can see your press climbing over the weeks. You can add warm-up sets, supersets and rest-timer holds, then drop the bench into a saved routine so it's ready the next time you train. LiftHero records what you log; it doesn't diagnose your form.
It primarily works the chest (pectoralis major), with the front deltoids and triceps as major assisting muscles. The upper back, forearms and legs stabilize the movement.
There's no single right number — it depends on bodyweight, training age and leverages. Focus on adding a little weight or a rep over time rather than comparing to others.
Not inherently. Most discomfort comes from flaring the elbows straight out, losing the shoulder-blade set, or too much volume. Tucking the elbows and retracting the shoulder blades usually helps.
Both work. The barbell loads the most weight and is easiest to progress numerically; dumbbells give a longer range of motion and train each side on its own. Many lifters use both.
For strength, about 3–6 reps across several sets; for size, about 6–12. Most lifters do 2–4 working sets, once or twice per week.
