HIIT – Every Damn Day
The lure of high-intensity interval training is undeniable; who doesn’t want to burn hundreds of calories in less than 30 minutes? But some research, like this study conducted by scientists in Brazil, has even the biggest meatheads questioning their “go hard or go home” ethos. Turns out that back-to-back burners can negatively impact your immune system, and nothing takes the edge off #BeastMode like the sniffles.
Instead: Try Tai Chi. This form of martial arts is a great option for fitness junkies who get the shakes from a straight-up rest day. Tai Chi delivers intensity, but in a calm, meditative way that promotes recovery between all-out sweat sessions.
