If you’re like me, you struggle to find the time in your day for just the basics like feeding the people in your house and keeping them reasonably clean and clothed. Finding an hour to exercise sounds daunting (also, I’m lazy and out of shape, so there’s more than just time constraints coming into play).
A study at McMaster University in Ontario says you might be able to see the same results in a much shorter period of time. This is just one study, so it’s nothing definite, and you should definitely get medical clearance before trying this. The researchers are not yet saying everyone should try this, so use caution if you’re going to even think about trying something like this.
Moving on. The study found that working out in 1-minute intervals at very high intensity (90% of maximum heart rate) and then taking it easy for a minute, then repeating 9 times, for a total of 20 minutes, led to results similar to people working out for much longer period of time at a lower heart rate.
Additional perks for diabetics: A small follow-up study showed that people with type 2 diabetes saw blood sugar regulation improvement after just ONE 20-minute session.
