Silicon Valley is ground zero for birthing biohacking habits, AKA changing the environment around or inside of you so you have more control over your biology. No time to eat? That’s okay, you can live off Soylent. Want your coffee to give you energy and fill you up? Add some butter and MCT oil.

Pondering a bucket list can be fun, but it also makes it more likely that you’ll actually climb that mountain, jump out of that airplane or swim with the dolphins in the time you have left on the Earth. 

There are some chaotic weeks where, between long working hours and a social life, you may just not get to spin class or yoga as much as you’d like. But if you’ve been stressed about only fitting in a sweat sesh one or two times a week, a new study reveals that there’s no need—because you can still reap the benefits of regular exercise with only a couple of vigorous workouts a week. Game changer.

When you’re feeling blah, a sweaty workout is a guaranteed mood-booster—because you never feel more badass than when you’re zig-zagging in the boxing ring or going all out in spin class, of course. (Shout out, endorphins!)
