Podcast: Fartleking

Five stars. (★★★★★)

I've been fartleking and didn't even know it! Research shows intense exercise - pushing beyond your comfort level - has unique benefits for longevity and brain health. According to Post Reports, fartlek is a Swedish term meaning "speed play," which is basically informal interval training. So for me, that could mean racing through every other song on the trail run. Go forth and fartlek.
