Smith Machine Bench Press
chest
What moves the load, and what it costs
6.0MET
Chest is the prime mover, with the front deltoid, triceps assisting. The fixed path removes balance and the safety hooks let you train close to failure without a spotter. It also removes the stabilising work, which is a real part of what a free-weight press trains.
Cue: Set the bench so the fixed bar path touches your lower chest — you cannot adjust the bar, so you adjust the bench.

The compendium files smith machine bench press under a category, not a lift. Read the ladder as position, not precision: this is heavier work than sitting quietly by a factor of 6.0, and at the top end of what a gym floor produces.
Turning that MET value into a real energy cost
- Map the movement to a published category. The compendium measures categories of conditioning work, never individual lifts, so smith machine bench press is filed under Resistance training (weight lifting, free weight or machine), power lifting or body building, vigorous effort.
- Take the category's MET value — 6.0. One MET is the cost of sitting quietly, so this is 6.0 times resting metabolism.
- Multiply by 3.5 to get millilitres of oxygen per kilogram per minute, the unit the MET is actually defined in.
- Multiply by your bodyweight in kilograms and divide by 200. The result is kilocalories per minute of work.
- Count working minutes only. Under load, not under the roof — a set of eight is about 25 seconds of the hour you were there.
kcal/min = MET × 3.5 × body mass (kg) ÷ 200 Smith Machine Bench Press: 6.0 × 3.5 × 70 ÷ 200 = 7.35 kcal/min

What is actually doing the work
| Muscle | Role | What it does here |
|---|---|---|
| ChestPectoralis major | Prime mover | Brings the upper arm across the body and forward (shoulder horizontal adduction and flexion). The clavicular head contributes more when the arm travels up and in; the sternal head when it travels down and in. |
| Front deltoidAnterior deltoid | Synergist / stabiliser | Raises the arm to the front (shoulder flexion) and assists horizontal adduction. Prime mover in overhead pressing, heavy synergist in every bench press. |
| TricepsTriceps brachii | Synergist / stabiliser | Straightens the elbow. The long head also crosses the shoulder, so it is stretched and loaded hardest with the arm overhead. |
The prime mover produces the movement against the resistance; synergists assist and stabilisers hold a joint still without moving it. An exercise trains the whole muscle it loads — there is no way to work only part of a muscle, and no exercise removes fat from the area around it.
Set up, then earn the rep
Smith machine, Bench. Every rep should look like the first one. The moment it stops looking like the first one, the set is finished.

- Lie back on the bench with your eyes roughly under the bar and your feet flat and heavy on the floor.
- Pull your shoulder blades down and together and keep them there for the whole set — this is what gives the shoulder a stable base to press from.
- Set the bench so the fixed bar path touches your lower chest — you cannot adjust the bar, so you adjust the bench.
- Unrack, take the bar over your chest with straight arms, then lower it under control to the lower half of your chest with your elbows at roughly 45 degrees to your torso.
- Touch, pause for a beat without relaxing, and press back to straight arms in one line.
- Keep the ribcage down and the backside on the bench throughout. Finish the set with the same bar path you started with.
Where this one breaks down
Not theory. These are the faults you correct on a gym floor, and the correction that actually works.
Flaring the elbows straight out to the sides.
A 90-degree elbow puts the shoulder joint at its most vulnerable angle for no extra chest recruitment. Tuck to roughly 45 degrees and the shoulder stops complaining.
Bouncing the bar off the chest.
The bounce hides a weak position and loads the sternum. Touch, pause for a count, then press — you will use less weight and get more from it.
Letting the shoulder blades come loose at the top.
Reaching for the ceiling at lockout unpacks the shoulder and shortens the range in the wrong place. Keep the blades set and let the bar finish over the shoulders, not the face.
Lifting the hips off the bench to complete a rep.
That is the point at which the set has finished. Rack it, drop the load and keep the backside down.
Regress it, or progress it

Prescription: load, reps, rest
లక్ష్యాన్ని చూసుకోండి, ఆ తర్వాత బరువు పెరుగుతున్నా టెక్నిక్ను మాత్రం స్థిరంగా ఉంచండి. ఇది ఈ పేజీ కోసం కల్పించినది కాదు, కదలిక యాంత్రికత నుంచే వచ్చింది: కాంపౌండ్ లిఫ్ట్ అనేక కీళ్లపై భారం వేస్తుంది, కాబట్టి ఇది ఎక్కువ బరువును తట్టుకుంటుంది, ఎక్కువ విశ్రాంతి అవసరం.
| Goal | Sets | Reps | Rest | Notes |
|---|---|---|---|---|
| Strength | 3–5 | 3–6 | 3–5 నిమి | ఎక్కువ బరువులకు ఎక్కువ విశ్రాంతి అవసరం. విశ్రాంతిని రెండు నిమిషాలకు తగ్గిస్తే బలం సెట్ కాస్తా కండిషనింగ్ సెట్గా మారిపోతుంది. |
| Muscle size | 3–4 | 6–12 | 90–180 sec | చాలా సెట్లను ఫెయిల్యూర్కు ఒకటి నుంచి మూడు రెప్ల లోపు వరకు తీసుకెళ్లండి. కచ్చితమైన రెప్ సంఖ్య కంటే ఒక్కో కండరానికి వారానికి మొత్తం హార్డ్ సెట్ల సంఖ్యే ఎక్కువ ముఖ్యం. |
| Endurance / fat loss | 2–4 | 12–20 | 45–75 sec | తక్కువ బరువులు, తక్కువ విశ్రాంతి. కొవ్వు తగ్గడం ఆహారంతో నిర్ణయమవుతుంది; ఇది ఆ సమయంలో కండరాలను కాపాడుతుంది. |
| First month | 2–3 | 8–10 | 2 min | ఫెయిల్యూర్కు చాలా ముందే ఆపేస్తూ, ప్రతి సెట్కూ అదే బరువుతో, చివరి రెప్లో కూడా కదలిక మొదటి రెప్లాగే కనిపించే వరకు. |
Time under load, in kilocalories
Read these as minutes of work, not minutes in the building. A set of eight takes about twenty-five seconds; the rest of the hour is rest, chalk and queueing.
Mapped category: Resistance training (weight lifting, free weight or machine), power lifting or body building, vigorous effort — 6.0 MET. That is the published category this movement is filed under, not a measurement of this specific lift.
Worked at 6.0 MET × 3.5 × 70 kg ÷ 200 = 7.35 kcal per working minute for a 70 kg adult. Scale it by your own bodyweight; the equation is linear. The full activity dataset lives at BurnLab.

The questions that come up on the floor
What muscles does the smith machine bench press work?
Smith Machine Bench Press is a compound movement in which the chest is the prime mover, assisted by the front deltoid, triceps. Brings the upper arm across the body and forward (shoulder horizontal adduction and flexion). The clavicular head contributes more when the arm travels up and in; the sternal head when it travels down and in.
Is the smith machine bench press good for beginners?
Yes. It rates 2 out of 5 for technical difficulty on this site — learnable in a session or two; low injury cost if it goes wrong. Start with the lightest sensible load and two or three sets of 8–10.
What can I do instead of the smith machine bench press at home?
The closest no-equipment substitute is the push-up, which trains the same prime mover through the same movement pattern. If you own a little equipment, the dumbbell bench press is closer still. It will not load you as heavily, so use higher reps and slower tempo to make up the difference.
How many sets and reps of the smith machine bench press should I do?
కండరాల పరిమాణం కోసం, 6–12 రెప్లతో 3–4 సెట్లు, 90–180 సెకన్ల విశ్రాంతి. బలం కోసం, 3–6 రెప్లతో 3–5 సెట్లు, 3–5 నిమిషాల విశ్రాంతి. మీ మొదటి నెలలో, 8–10 రెప్లతో 2–3 సెట్లు, ఫెయిల్యూర్కు చాలా ముందే ఆపేయాలి. ఈ పరిధుల్లో ఏదైనా సరే, కచ్చితమైన రెప్ సంఖ్య కంటే ఒక్కో కండర సమూహానికి వారానికి మొత్తం హార్డ్ సెట్ల సంఖ్యే ఎక్కువ ముఖ్యం.
Does the smith machine bench press burn fat from the chest?
No. No exercise removes fat from the area it trains — spot reduction has been tested repeatedly and does not happen. Training the chest builds the muscle underneath; where body fat is lost from is decided by an overall calorie deficit and by your genetics, not by which exercise you chose.
Muscle roles follow standard kinesiology references and are described by joint action rather than by gym convention — see how this site is built. Energy figures are derived from the 2024 Adult Compendium of Physical Activities. Every reference is named and dated on the sources page. General information only — not medical or coaching advice. Load, form and progression should be adjusted to your own experience and any injury history. When in doubt, get coached in person.
