Muscles worked
The decline bench press trains the same muscles as the flat bench press, but the angle shifts the emphasis towards the lower part of your chest. Your triceps help straighten your arms, and the front of your shoulders usually does a little less than on a flat bench. The bar travels a shorter distance, so many people lift about as much as on a flat bench, sometimes more. Your legs are hooked under the pads and cannot drive into the floor.
Common mistakes
- Unracking the bar on your own. From a decline bench it is hard to bring the bar out over your chest without losing your position. When the weight is heavy, ask someone to hand it out and help you rack it.
- Setting the bench steeper than needed. A steep angle makes the movement very short, and many people feel an unpleasant pressure in their head. A slight decline, roughly 15 to 30 degrees, is usually enough.
- Sitting straight up after the set. Your head has been lower than your hips, and many people feel light-headed if they get up quickly. Rack the bar, lie still for a couple of breaths, then sit up slowly.
Variations and alternatives
- The bench press on a flat bench is the main lift, and the obvious choice when there is no decline bench or spotter.
- Chest dips also work the lower chest, with your body weight and a forward lean.
- Cable flyes with the pulleys set high and a downward pull target the same part of your chest without a bar.
Sets and reps
The decline press usually comes second in a session, after a flat bench or dumbbell press. In that slot, 6 to 12 reps over 3 to 4 sets suits building muscle. As a heavy main lift with 3 to 6 reps it needs a spotter, as decline benches rarely sit in a rack with safety arms. The guide to sets and reps explains how reps and sets relate to your goal.
Add a rep or two at a time, and raise the weight by 2.5 kg once every set hits the top of its rep range. That is progressive overload.
