Welcome to the Get Fit Guys, quick and dirty tips to slim down and shape up.

My name is Ben Greenfield. I'm the Get Fit Guy, and in today's episode, I'm going to give you

six hacks to get fit in less time. Now, I recently tweeted the results of a recent study that indicated no difference in

increased fitness with swimming 50s versus swimming 100s. Now, in this study, 24 swimmers were

divided into a short interval training group that did eight weeks of workouts that consisted of 12 to 16,

50 meter repeats, with 15 seconds of rest in between each repeat.

And then there was a long interval training group that did 6 to 8, 100 meter repeats with 30 seconds rest.

And then finally there was a control group.

Now, they measured things like aerobic performance, lactic acid threshold, and heart rate recovery,

and also, of course, overall swim performance. Now it acid threshold, and heart rate recovery, and also,

of course, overall swim performance.

Now, it turns out after eight weeks of training that the short interval, the 50-meter

group, and the long interval, the 100-meter group, both experienced very similar improvements

in swimming performance and aerobic adaptations.

And the problem is, once you match the workouts for distance and time, they're actually pretty

similar.

So this doesn't really mean that a 50-meter workout is better than 100-meter workout because,

frankly, they're both swimming similar distances.

So at first glance, there isn't really much of a time-hacking exercise take away from

this study, but rather

just an indication that doing short, hard repeats is just as effective as doing slightly longer

repeats, assuming volume is held constant.
