Bench Press vs Chest Press Calories: Which Burns More?
Bench press vs chest press machine calorie burn compared with the Compendium MET model. At the same effort and time they burn about the same; effort, rest and session length make the difference.
At the same effort and the same session time, bench press and the chest press machine burn about the same number of calories. For an 80 kg (176 lb) lifter, 3 sets of 10 at moderate effort burn about 21 calories on either one, rest between sets included. Training heavy (vigorous effort) raises that to about 36 calories.
The difference between the two lifts comes from how you train them, not from the machine: effort, rest between sets and total time drive the calorie burn.
Quick Comparison
| Metric | Bench Press | Chest Press | Winner |
|---|---|---|---|
| Calories per set of 10 (80 kg lifter, moderate) | 2.3 cal | 2.3 cal | Tie |
| Calories per 3×10 incl. rest (80 kg, moderate) | 21 cal | 21 cal | Tie |
| Calories per 3×10 incl. rest (80 kg, vigorous) | 36 cal | 36 cal | Tie |
| Stabilizer engagement | High | Low | Bench Press |
| Ease of use | Moderate | Easy | Chest Press |
| Safety solo | Lower | Higher | Chest Press |
Side-by-Side Calorie Comparison
Both calculators use the same MET values, so at equal effort and time the numbers are identical. The useful comparison is moderate versus vigorous effort.
At Different Body Weights (3 × 10 reps, bench press or chest press)
| Body Weight | Moderate (MET 3.5) | Vigorous (MET 6.0) |
|---|---|---|
| 60 kg | 15.8 cal | 27.0 cal |
| 70 kg | 18.4 cal | 31.5 cal |
| 80 kg | 21.0 cal | 36.0 cal |
| 90 kg | 23.6 cal | 40.5 cal |
| 100 kg | 26.3 cal | 45.0 cal |
At Different Rep Schemes (80 kg lifter, either exercise)
| Sets × Reps | Session Time (incl. rest) | Moderate | Vigorous |
|---|---|---|---|
| 3 × 8 | 4.2 min | 20 cal | 34 cal |
| 3 × 10 | 4.5 min | 21 cal | 36 cal |
| 4 × 10 | 6.5 min | 30 cal | 52 cal |
| 4 × 12 | 6.9 min | 32 cal | 55 cal |
| 5 × 10 | 8.5 min | 40 cal | 68 cal |
The weight on the bar or the machine stack changes these numbers little; the effort level, rest and the number of sets change them a lot.
Why the Numbers Are the Same
1. The MET Values Don't Separate Machines From Free Weights
The Compendium of Physical Activities, the standard reference for exercise calorie estimates, rates resistance training by effort, not by equipment. Its entries for weight training cover free weights and machines alike: 3.5 MET for moderate effort (code 02054) and 6.0 MET for vigorous lifting (code 02050).
2. Stabilizers Add Little Energy
Bench press does recruit more stabilizers: rotator cuff, serratus anterior and some core and leg drive. That matters for strength and technique, but the extra energy is small next to the energy your body burns across a whole session, rest included. There is no reliable measurement showing a fixed percentage difference between the two lifts.
3. Rest and Session Time Dominate
Weight-training METs are averages over a session that includes rest. Cutting rest from 90 to 60 seconds shortens the session, so 3 × 12 then takes 3.8 minutes and burns about 18 calories instead of 22 for an 80 kg lifter. What drives the per-hour burn is how hard you work while you are there.
4. Effort Is What You Control
If you push closer to failure, keep rests short or use supersets, you move toward the vigorous value. That applies on the machine just as much as on the bench.
The Formula (Same for Both)
Calories = MET × body weight (kg) × time (hours)
MET = 3.5 moderate (Compendium 02054), 6.0 vigorous (Compendium 02050)
Time for sets × reps = sets × reps × 3 s + (sets − 1) × 90 s rest
Worked example: an 80 kg lifter does 3 × 10 at moderate effort. Time: 3 × 10 × 3 s + 2 × 90 s = 270 s = 4.5 minutes. Calories: 3.5 × 80 × 4.5 ÷ 60 = 21 kcal, whether on the bench or the chest press machine.
When to Choose Each Exercise
Choose Bench Press When:
- You have a spotter available
- You want to build functional strength
- Training for sports performance
- You have good shoulder health
Choose Chest Press When:
- Training alone without a spotter
- You're a beginner learning the movement
- Rehabilitating from injury
- Wanting to isolate chest muscles
- Finishing a workout with burnout sets
Combined Approach: Best of Both
Many effective chest workouts use both exercises:
| Exercise Order | Exercise | Purpose |
|---|---|---|
| 1st | Bench Press | Heavy compound, max strength |
| 2nd | Incline Bench | Upper chest development |
| 3rd | Chest Press | Volume without fatigue concern |
| 4th | Flyes | Isolation and stretch |
Sample Workout Calorie Burn
| Exercise | Sets × Reps | Calories |
|---|---|---|
| Bench Press | 4 × 6 | 27 cal |
| Incline Bench | 3 × 10 | 21 cal |
| Chest Press | 3 × 12 | 22 cal |
| Dumbbell Flyes | 3 × 15 | 25 cal |
| Total | ~95 cal |
For an 80 kg (176 lb) lifter at moderate effort (MET 3.5), 90 seconds rest between sets.

Conclusion
At the same effort and session time, bench press and the chest press machine burn about the same number of calories. Choose between them for strength, safety and convenience rather than calorie burn: bench press builds more stabilizer control and free-weight strength, while the chest press is easier to use alone and works well as a finisher. To burn more on either, train harder, keep rests shorter or add sets.
