This training method burns a whopping 400 calories in just 20 minutes. Check it out
Burn 400 Calories in 20 Minutes
So one day you woke up and discovered that the carb monster has surreptitiously absconded with your abs. Pffft! Gone. Left in their place is a fleshy version of Nebraska terrain – smooth, featureless. If you were driving a tiny car across it, you’d eventually fall asleep from boredom and not wake up until you crashed into the base of Devil’s Tower in nearby fleshy Wyoming.
If you’re like most people, you try to get your abs back by doing cardio or stuff that makes you huff and puff and sweat. The trouble is, that’s the wrong way to go about it.
Consider that biking for a half hour burns about 150 calories, or that even high-intensity stuff like hiking uphill, playing some serious b-ball, or even heavy weightlifting only burns about 220 calories in the same time frame. Even if you did an hour of any of those activities a day, you’d only burn about a half pound of fat a week. No, when it comes to burning fat, you’re far better off restricting your eating.
However, there seems to be one physical activity that’s an exception to the rule. It seems that kettlebells, used in a particular way at least, can burn an amazing 400 calories in just 20 minutes.
The Study
A couple of sports scientists from the University of Wisconsin wanted to see how many calories one-arm kettlebell snatches would burn, so they devised a formula and protocol.
- Subjects – a mix of males and females, all experienced kettlebell users – were allowed to choose between 12, 16, or 20-kilogram kettlebells.
- Subjects undertook an overly complicated test that essentially had them see how many one-arm kettlebell „snatches“ they could do in one minute. Researchers described this as swinging a kettlebell one-handed between their legs and up and over their head, which also sounds like an American kettlebell swing depending on how exactly they performed the movement. The exact exercise probably isn’t as important as the training method however.
- They then divided that number of snatches by 4 to get the value x. So let’s say they did 24 one-arm snatches in one minute. If you divide that by 4, you get 6.
- Trainees were then asked to do X one-arm kettlebell snatches (6, in our example) for 15 seconds with their right arm.
- They then rested for 15 seconds.
- Then they did 6 one-arm kettlebell snatches with their left arm, after which they rested for 15 seconds.
- They continued in this manner for 20 minutes.
What They Found
Based on their use of oxygen, the trainees burned 13.6 calories (kilocalories, to be technically correct) every minute, but they also measured their blood lactate levels and found they were burning an additional 6.6 calories per minute.
„So they were burning at least 20.2 calories per minute, which is off the charts,“ exclaimed one of the researchers. „That’s equivalent to running at a 6-minute mile pace. The only other thing I could find that burns that many calories is cross country skiing uphill at a fast pace.“
What To Do
Clearly, if reacquiring your abs is your priority, combining this 20-minute kettlebell protocol with some degree of calorie deprivation is the quickest way to go about it. However, you probably don’t need to get hung up on the exact formula and the exact number of swings you need to do per 15-second period. Your body will tell you if you’re busting your ass enough.
