So you and your partner want a new regular activity. Maybe you want to lose weight. You could find something that satisfies both those needs. You could compare local gym memberships but, you likely won’t end up actually going to the gym at the same time often. You say you will but, between traffic, various schedules, and different wakeup times, you’ll give up on coordinating it—you’ll just go separately. You may hit those weight loss goals but, you won’t wind up spending much more time together, and you won’t have a new regular activity in your life. You can just go to the gym whenever…or not. Nobody will notice if you don’t. Consider, instead, taking up a sport with your partner. Your team will rely on you, so you’ll have to show up at game times—it holds you accountable. There are actually a lot of perks of taking up a sport with your partner.
You’ll be happy at the same time
You’ll get those endorphin boosts at the same time. You won’t have one happy person, and one cranky person killing the happy one’s buzz. You’ll both get that post-workout lift at the same time.
