Chest Press Machine

The machine chest press is a seated press in which you push a pair of handles forward along a fixed path, with the weight supplied by a stack or plates. It works the chest, the front of the shoulders and the triceps, and because the machine guides the movement it is widely used by beginners and for hard chest sets without a spotter.

How to do it

Step by step

  1. Adjust the seat so the handles line up with the middle of your chest when you sit with your back against the pad.
  2. Sit tall with your back and head on the pad and your feet flat. If the machine has a foot lever, use it to bring the handles forward to the start position.
  3. Grip the handles with your knuckles in line with your forearms, and set your shoulder blades back against the pad.
  4. Press the handles forward, and slightly together if the machine converges, until your arms are straight without snapping the elbows.
  5. Let the handles come back under control, taking about two seconds, until you feel a stretch across your chest with your elbows about level with your torso.
  6. Turn the rep around just before the weight stack touches down, keeping your shoulder blades on the pad, and press again.
  7. After the last rep, bring the handles back slowly (with the foot lever, if fitted) and let the weight settle before you let go.
Coaching cues
  • Handles in line with your mid-chest
  • Shoulder blades back on the pad
  • Press forward and slightly together
  • Elbows level with your torso at the stretch
  • Smooth turnaround, stack never touches
  • Knuckles in line with your forearms

In VALDA, these cues are one tap away on the exercise while you train.

Common faults

What goes wrong, and the fix

Seat set too low

Fix: Set the seat so the handles line up with the middle of your chest.

Shoulders shrugging and rolling forward

Fix: Keep your shoulder blades back on the pad and press with your chest.

Resting the stack between reps

Fix: Turn each rep around just before the weight stack touches down.

Cutting the range short

Fix: Let the handles come back until your elbows are about level with your torso.

Bouncing out of the bottom

Fix: Take about two seconds to bring the handles back, then press smoothly.

Wrists bent back

Fix: Grip so your knuckles stay in line with your forearms.

What the research says

Muscle growth · first choiceRehab & prehab · first choiceGeneral fitness · first choiceEndurance · first choiceStrengthFat loss & conditioning

  • Machines and free weights — A meta-analysis of head-to-head studies found machine and free-weight training produce similar muscle growth, while strength gains are specific to the equipment you train and test on.
  • Load by goal — Research comparing loads finds maximal strength favours heavier loads, while muscle growth is similar across a wide range of loads when sets are taken close to failure.
  • Effort — Studies show sets that finish a few reps short of failure capture most of the growth benefit, and true failure adds only a small extra return. A machine can be taken close to failure without a spotter, and many lifters use it for drop sets.
  • Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns. Around 10 or more hard sets a week has been associated with more growth than fewer than 5, and training a muscle about twice a week is a common way to spread that volume.
  • Range of motion — Research finds full range of motion gives equal or greater gains than partial range, although upper-body comparisons are few. On most machines, seat height sets how far the handles travel.
  • Rest — In trained lifters, rests of about 3 minutes between sets have produced greater strength and size gains than 1-minute rests, largely because they let each set carry more load.
