Whether going for a hike, taking a spin class, or lifting weights, breaking a sweat with your significant is a good date idea that’ll keep both you and the relationship healthy. Next time you and your better half are debating between a Netflix marathon or something more active, opt for the more heart-pumping activity. (You can always queue up “House of Cards” while you cool down afterwards.)Here are a handful of reasons to exercise as a couple.1. You’re more likely to do it. A lot of us need some encouragement — and sometimes downright nagging — to exercise. This is where a significant other comes in really handy. A January 2015 study published in JAMA Internal Medicine looked at how likely people were to change their habits for the healthier, like quitting smoking, starting to be active, or losing weight, in relation to what their partner did. What they found was that people were more successful in adopting new, healthy habits if their partner did it, too.2. It’ll improve your sex life. It’s pretty obvious that not working out makes you feel sluggish. Short bouts of intense exercise have been linked in previous studies with increased testosterone levels, which makes you down for the get down. Studies have also reported women were more sexually responsive following vigorous exercise.3. It boosts your self-esteem. …which leads to more time beneath the sheets. Another study from the University of Arkansas found that the more women exercise, the more attractive and desirable they feel. Feeling confident and sexy, combined with that spike in testosterone, is a recipe to put you in the mood.4. You’ll spend more time bonding. Look at workouts not as a chore, but as a way to spend quality time together. It’s an opportunity to get fit and feel good, while also partaking in an activity together. Not to mention, it gives you a common hobby to talk about and work at together — a great way to strengthen your bond.Related Articles:5 Secrets to a Successful Relationship, From a Couples Therapist
