Bench press: technique and mistakes to avoid
Informational content: this is not a substitute for medical advice. Check with a doctor before starting a training program, especially if you have a health issue or any pain.
The bench press is the king of upper body exercises, the one everyone wants to load up. But it is also one of the most poorly performed in the gym: too heavy, too fast, with no setup. The result is aching shoulders and stalled progress. Here is how to do it right, and the mistakes that cost you kilos and sometimes an injury.
Which muscles does the bench press work?
The bench press is a compound exercise that works three main muscles:
- The chest, the main driver of the movement.
- The front delts, at the front of the shoulders.
- The triceps, which finish the press.
Done well, it is one of the best builders of strength and mass for the whole upper body.
Setup, the base of everything
A good bench press is won before you even unrack the bar. Take the time to set up:
- Eyes under the bar. Lie down so the bar sits over your eyes, not your neck.
- Feet firmly planted. Flat on the floor, under or slightly behind your knees, for a stable base.
- Shoulder blades pinched. Retract your shoulders down and back, as if tucking them into your pockets. Push your chest up.
- A slight arch. A natural curve in the lower back, with your glutes always in contact with the bench.
This position builds a solid base, protects your shoulders, and slightly shortens the bar's path.
Grip and bar path
Set your hands a little wider than shoulder width. At the bottom of the movement, your forearms should be roughly vertical. The bar rests in your palm, stacked over the forearm, wrists straight, never bent back.
As for the path, the bar does not come down on your collarbone but toward the lower chest, around the sternum. Your elbows stay at about 45 to 75 degrees from your torso, never fully flared to 90 degrees. Lower under control, touch your chest without bouncing, then press the bar back slightly toward your eyes.
The most common mistakes
Most problems come from too much load and a sloppy setup. Here are the classic faults and how to fix them:
| Mistake | Fix |
|---|---|
| Bouncing the bar off your chest | Control the descent and pause briefly |
| Elbows flared to 90 degrees | Tuck elbows to 45-75 degrees from the body |
| Glutes lifting off the bench | Keep the hips anchored, lower the load |
| Partial range of motion | Touch your chest on every rep |
| Shoulder blades not retracted | Pinch your shoulders before unracking |
| Wrists bent back | Bar in the palm, wrists straight |
If you remember one thing: most of these mistakes disappear the moment you take a little weight off the bar. Ego lifting is the worst enemy of a good bench press.
Safety first
The bench press is one of the few exercises where you can get pinned under the bar. Train in a rack fitted with safety pins set just above your chest, or with a spotter. If you have neither, stay cautious with the load and skip the collars: if you fail a rep, you can tilt the bar to slide the plates off.
How to progress on the bench press
Once your technique is clean, progress follows a simple rule: progressive overload. Add a rep or a bit of load as soon as your set feels easy, without ever sacrificing your setup. Small, regular increases session after session beat any reckless max attempt. Log your performance so you know exactly what to beat next time.
Frequently asked questions
What grip width for the bench press?
Set your hands a little wider than your shoulders, so your forearms are vertical at the bottom of the movement. A grip that is too wide or too narrow reduces your power and stresses the joints.
Do you need to touch your chest on every rep?
Yes. A full range of motion, with the bar touching your chest without bouncing, stimulates the muscles better and keeps your progress comparable from one session to the next. Just avoid bouncing the bar.
Why do my shoulders hurt when I bench press?
Usually because your elbows are too flared and your shoulder blades are not retracted. Tuck your elbows to 45-75 degrees from your body and pinch your shoulder blades before each set to protect the joint.
Barbell or dumbbell bench press?
The barbell lets you load heavier and build strength. Dumbbells offer more range of motion and fix side to side imbalances. Both are complementary, so alternate based on your goal.
A clean, consistent bench press always pays off, as long as you measure your progress. By logging your sets, loads, and estimated 1RM in Musku, you see exactly whether your bench is moving up or stalling, and you can note your execution cues to reproduce the same setup every time. Your technique stays consistent, and your numbers tell a story of real progress rather than a vague impression.
