![]() ![]() Of course, you could slip on those sneakers and go for a run outside, but that’s not always possible. Still, the results of the study are still probably solid enough to provide some guidance to those who regularly expose themselves to the torture of indoor cardio and want to spend their time in the most efficient way.Walking or running is one of the best all-around exercises you can do. It's hard to believe that some waif-like, Ariana Grande type who prances from step to step, alighting on them like a dragonfly skittering across a pond, would burn the same amount of calories as some Marvel Juggernaut-clone who plods along, causing the Earth to shake with each step. Limb length and size/weight, by logic, has to make a difference.Ĭase in point, consider the stepmill, which, amazingly, ranked second in total calories expended. Thirdly, body anthropometry must surely play a role in how many calories a body expends using a certain piece of equipment. Secondly, some test subjects might have been more familiar with certain pieces of exercise equipment, which may have resulted in lower energy expenditures on the equipment they were most comfortable with. The researchers then extrapolated what the results, calorie-wise, would look like after 30 minutes.Įxtrapolation is generally fine, but it leaves room for all kinds of inaccuracies. For one thing, the subjects only exercised for 5 minutes at a time at the three different RPEs (which are subjective anyhow). That being said, you need to look at some of the limitations of this study. It makes sense that if you commit yourself to the drudgery of indoor-machine cardio work, you'd want to use the piece of equipment that gives you the greatest return, calorie-wise. In other words, the researchers did all the stuff they were supposed to do to ensure that the results had some integrity. (For sake of comparison, 11 is fairly light 13 is considered "brisk," and 15 is considered pretty hard but sustainable.) Each subject completed 5-minute bouts on each machine at RPE workloads of 11, 13, and 15 on the 6-20 Borg scale. They were also instructed on the fine points of RPE, or rate of perceived exertion. Without going into too much detail, take it from me that the researchers went to great lengths to ensure that each person was permitted to become familiarized with each machine before testing, allowed ample warm-ups, and was tested on only two machines a day to allow ample rest. Airdyne Bike (the kind that has a fan that whips your 'do like an open convertible).Stepmill (one of those revolving staircase things).Each subject was tested on all of the following 10 machines: Researchers cajoled 16 young adults, each presumably comfortable with long stretches of boredom, to participate. Surprisingly, at least to me, it was the common treadmill that took the calorie-burning prize. It's with them in mind that I present the results of a recent study that compared 10 common indoor exercise machines to determine which was best, i.e., which one burns up the most amount of calories. ![]() I think these machines are much better suited for building "metabolic capacity" so that you won't go into oxygen debt during some future set of deadlifts.Īnyhow, there are always going to be people who rely on cardio machines to lose weight. You're much better off, weight-loss wise, in saying no to a beer, pushing away that dessert, or even mixing up your tuna salad with a teaspoon of mayo instead of a tablespoon. ![]() I maintain that only soulless human drones, the kind suited for assembly line piecework at a factory, can endure the mind-numbing boredom of peddling, stepping, or striding long enough and hard enough to burn up any significant amount of calories. It's damn hard to burn anywhere close to 300 calories during a 30-minute stint on any type of indoor exercise machine. Cardio machines pretty much suck for the purposes of fat loss.
