The Study
Caloric Expenditure of Aerobic, Resistance, or Combined High-Intensity Interval Training Using a Hydraulic Resistance System in Healthy Men
This study watched 9 guys do four different workouts and measured how many calories they burned. It says they burned more calories with one machine — but that doesn’t mean the machine makes you healthier or helps you lose weight. It just shows what happened during those 30-minute sessions.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — HRS HIIT burns nearly 40% more calories per minute than regular weight training and is the most intense option tested.
- 2HRS HIIT burned 12.6 kcal/min, heart rate hit 156 bpm, and felt like a 16/20 effort.
- 3Resistance training burned 8.8 kcal/min, treadmill 9.5, cycling 9.2.
- 4Treadmill burned the most fat.

Doing super intense workouts in short bursts burns more calories in less time than going easy on the exercise.
When doing a 30-minute workout on a hydraulic machine with short bursts of maximum effort, your heart beats much faster than when you're lifting weights, running, or biking at a steady pace.
When doing a high-intensity workout on a hydraulic machine, your body burns more sugar (carbs) for energy than when you lift weights, run, or bike at the same time.
People feel like they’re working much harder during a 30-minute hydraulic machine HIIT workout than during weightlifting, running, or biking, even though they’re resting part of the time.
Doing a 30-minute workout on a hydraulic machine with short bursts of all-out effort burns more calories than the same amount of time lifting weights, running on a treadmill, or riding a bike.
Resistance training is energetically inefficient in terms of total caloric expenditure due to predominant eccentric muscle actions and prolonged inter-set rest periods.
