You already know that you need to burn calories to lose weight, right? So it makes sense that longer exercise sessions will burn more calories.
Hold on one second…
The “more is better” myth needs busting. In fact it needs to be smashed into bits, put in a box, and thrown off a bridge on a particularly chilly morning.
We can see why this misconception is popular. It DOES make sense that longer exercise sessions will burn more calories/fat and help you lose more weight.
But the problem with long, slow cardio workouts (like cardio machines at the gym) is that they just burn calories there and then. Let’s say you burn 400 calories doing cardio. You could easily eat these calories back (some fancy mocha-frappuchino-latte-smoothies are more than 400 cals!) And those 400 calories aren’t an accurate reflection. You would have “burned” around 70 calories just walking around. So actually, you’ve only burned an extra 330 calories.
But the main problem with “more is more” cardio is that is does NOTHING for your metabolism after you finish. Step off that cardio machine, and your body goes straight back to normal calorie burning levels.
Which is why our SFTW workouts only last 20 minutes! But they are MORE effective than 60+ minutes regular cardio.
We use a training method called HIIT (high intensity interval training) so you work as hard as you can, then have a short break, then work super-hard again. Your body never really gets a chance to recover during the 20 minutes, but the rest periods make you feel capable of carrying on.
The result? Sweat pouring, heart beating, fat burning, calories buggering off!
In fact, you will burn MORE calories all day long when you do 20 minutes of HIIT. Because the intensity of the workout ramps up your metabolism, keeping you burning calories for hours (some studies suggest 24+ hours!) after.
Still wish “that exercise sessions only had to last 20 minutes”?
They do. 20 minutes hard work is all it takes, if you know what to do. The rest is just a waste of your precious time - and we know you don’t have any spare time to spend going nowhere on the treadmill!
