Muscles worked
The incline machine chest press trains your chest, the front of your shoulders and your triceps. The angled path usually gives the upper chest, the part attached to your collarbone, more work than a flat chest press, and your shoulders take a bigger share too. The machine guides the path, so the small muscles around your shoulders have less to do than with dumbbells. That makes it easy to learn and easy to load, even late in a session.
Common mistakes
- Skipping the set-up. The machine is often still set for whoever used it last. If the handles sit well above your upper chest, it turns into more of a shoulder press. Adjust the seat before you add weight.
- Your shoulders creep up towards your ears. When it gets heavy, many people call on their neck and upper traps. Keep your shoulders down throughout the set. If you cannot, the weight is too heavy.
- Your reps get shorter as the weight goes up. Lower until the handles are just in front of your chest and you feel a clear stretch, and go lighter if you cannot get there.
Variations and alternatives
- The incline dumbbell press trains the same angle with free weights, each arm working on its own.
- The incline bench press with a barbell is a step towards heavier lifting and asks more of your balance.
- The machine chest press presses straight forward, without the incline.
- Decline push-ups, with your feet raised, give a similar angle at home.
Sets and reps
This exercise is best suited to building muscle, with 8 to 12 reps over 3 to 4 sets a common set-up. Heavier sets of 6 to 8 reps work, but for pure strength the incline barbell press is more usual. For endurance, or as the last chest exercise of the session, 12 to 20 reps suits. With a fixed path you can go close to the limit without a spotter, but leave one or two reps in reserve on most sets. See the guide to sets and reps.
Weight stack steps can be large. Stay at the same weight until you reach the top of your range on every set, then go up one step. That is progressive overload on a machine. Note the seat setting too.
