How to burn The MOST calories?

any intense cardio like running, swimming, cycling. it depends how long you can sustain it. for example if you burn 600 calories per hour running and 500 calories per hour cycling, but you can cycle for 1 hour at that rate but only run for 30 minutes, then you'll only burn 300 calories running while you burn 500 cycling.

the highest rate I've seen is cranking the treadmill to 15 mph, burns like 1800 calories per hour, but I can only run 30 seconds at that pace.

HIIT intervals are efficient.

High intensity or crossfit type workouts cause your body to keep burning calories even after you stop the workout. However if you push yourself hard enough then almost any machine will get you a good burn. You want to stay in your target heart rate for at least 30 minutes for max burn.

On the elliptical, I set resistance to high, 13-15 (if max is 20) and ramp low. On the spin bike, I increase the resistance and do a standing climb and I stay standing for most of the hour. Outdoors, I like to simply run up and down a hill. Cycling is also good especially if you have hills to climb.

What machine or workout burns the most calories.

@Jesusjohnjames
The one you can do for the longest duration with a reasonably high but sustainable intensity level.
Remember it's you not the machine that burns calories, you are the limiting factor and not the machine.

If I only had 8 minutes then 2000m on the rowing machine flat out would probably be my highest possible burn.
If I have anything from 30mins to several hours then it would be cycling - because I'm a cyclist and not because the cycle burns more than an elliptical for example.

HIIT isn't a big calorie burner - it's very short duration and a proportion of the short duration is low intensity recovery time.
Ditto for sprints - very, very short duration.
The after burn of using calories after workout has finished (EPOC) is often exaggerated and generally pretty insignificant.

But please don't exercise just for calorie burns!
Think of your health and fitness goals. Plus enjoyment and fit with your lifestyle - that ultimately makes it sustainable.

I was going to say that I burned the most calories when I left dinner in the oven too long... and then I had second thoughts.

Aw, I wish you had said it. That would have been pretty funny.

Do you need to use machines? Swimming is one of the best calorie burning exercises, not to mention working pretty much all of the major muscle groups.

For me, I found a local, "boot camp," that makes me burn the most. I've been going for almost 2 years so it's constant. I've made a lot friends there so that pushes me harder every time I go.
