How to bench press safely

The bench press is one of the most useful upper-body lifts, and one of the few where a missed rep can pin a bar on your chest. Set it up properly and it’s a safe, steady way to build strength.

Before you load the bar

Most bench press accidents happen because someone trains alone, heavy, with nothing to catch the bar. The fix is simple and takes thirty seconds: set up a way to fail safely before you do a single rep.

Many gyms have a bench press with safety arms, or a power rack you can put a flat bench inside. Set the safety arms or pins so they sit just below the height of your chest when you’re lying on the bench with a normal arch. If you lower the bar and can’t press it back up, you let it come down onto the arms rather than onto you.

If your gym only has a standard bench with no safety arms, either ask someone to spot you, or train with dumbbells instead. A dumbbell bench press works the same muscles, and if a rep fails you can lower the dumbbells to your sides.

One more thing to skip if you train alone: collars. On a bench with no safety arms, some lifters leave collars off so they can tip the plates off one side in an emergency. That’s a last resort, it’s noisy, and it can hurt someone nearby. Safety arms or a spotter are far better.

Setting up on the bench

1. Eyes under the bar. Lie down so the bar is roughly above your eyes. Too far down the bench and you’ll hit the hooks when you press; too far up and unracking is awkward.
2. Feet flat. Put your whole foot on the floor, a little behind your knees if that’s comfortable. Your feet stay planted for the whole set.
3. Shoulder blades back and down. Imagine tucking them into your back pockets. This gives you a stable base and keeps the shoulder joint in a better position.
4. A small, natural arch. Your lower back can lift slightly off the bench, but your bottom and upper back stay in contact.
5. Grip. Hands a little wider than shoulder-width, with the bar in the heel of your palm and your wrists stacked over your elbows. Wrap your thumbs around the bar. A thumbless grip makes it easier for the bar to roll out of your hands.

The rep itself

Unrack the bar with straight arms and move it so it sits above your shoulders. Take a breath and hold your middle firm.

Lower the bar under control towards your lower chest, around the bottom of your breastbone. Your elbows should travel at roughly 45° from your body: not flared straight out to the sides, and not tucked tight against your ribs. Touch your chest lightly. Don’t bounce.

Press back up, and slightly back towards your shoulders, breathing out as you press. Finish with straight arms but don’t slam the elbows locked. Pause, breathe, and go again.

When the set is done, press to straight arms and move the bar back until it touches the uprights, then lower it into the hooks. Look at the hooks, not the ceiling.

Working with a spotter

A good spotter stands behind your head, hands close to the bar but not touching it. Agree three things before the set:

• How many reps you’re going for.
• Whether you want help with the lift-off.
• The signal for “take it”. Most people say it out loud. If the bar stops moving upwards, the spotter takes it.

The spotter should help you finish the rep and rack the bar, not lift it for you halfway through a set. If you need someone to do half the work, the weight is too heavy for today.

How to fail a rep safely

Every lifter misses a rep eventually. Plan for it:

• With safety arms: lower the bar to your chest, then let it rest on the arms. Slide out from underneath towards the top of the bench, then unload it.
• With a spotter: say the word and keep pushing while they take the bar.
• With dumbbells: lower them under control to your chest, then to your sides, and sit up with them resting on your thighs.

The best way to avoid failed reps is to leave one or two in the tank on most sets. You get almost all of the benefit without grinding through reps where your form falls apart.

Common mistakes

• Bouncing the bar off your chest. It takes work away from your muscles and is hard on your ribs.
• Elbows flared at 90°. Many people find this uncomfortable on the front of the shoulder. Bring them in a little.
• Bottom lifting off the bench. It usually means the weight is too heavy. Feet stay down, hips stay down.
• Lowering to your neck or upper chest. Aim lower, towards the bottom of the breastbone.
• Adding weight every session no matter what. Progress is great, but only add weight when every rep looks the same. See our guide to progressive overload.

Building up

Start with an empty bar or light dumbbells, even if you’ve lifted before. Do a few warm-up sets that get gradually heavier before your working sets. For most people, three sets of eight to ten reps with a weight that leaves a couple of reps spare is a sensible start.

The NHS recommends that adults do activities that strengthen all the major muscle groups on at least two days a week. A bench press, alongside a squat or leg press, a row and a hinge, covers a lot of that in one session. If you want a plan that puts this together, our beginner 3-day gym plan is a good place to start.

Write down every set: the weight, the reps and how it felt. Next time, try to beat it by one rep or a small amount of weight. That’s how people get stronger over months rather than weeks. Our guide to using a workout log explains how.

When to stop

Stop the set if you feel sharp pain in your shoulder, elbow or chest, or if you feel dizzy or unusually breathless. Shoulder pain that keeps coming back is worth getting checked by a GP or physiotherapist before you carry on pressing.
