Over the years, countless studies have shown that exercising with a buddy—whether it’s your BFF, your mom, your significant other, or whoever else—truly is one of the best ways to make sure you break a sweat on a consistent basis. The psychology behind this idea is fairly simple: If someone else is relying on you, you may be less likely to last-minute bail than you would if you’re only relying on yourself. What’s more, when you finally do get out there, your workout buddy may also encourage you to hustle harder than you would have if you were trudging through your routine solo. And perhaps most importantly, let’s not forget that exercising with a pal can also be straight-up fun! Whether you choose to go on a bike ride through your city, plan a day hike through the woods, or even check out one of those crazy trendy workout classes, like goat yoga (wtf?!), living that active life with a buddy is a rewarding way to spend time together—and stay fit along the way.
