I've been married to my husband for almost 17 years.

Whenever I see a couple working out together, I can't help but wonder what it would be like to share an exercise routine with a partner.My husband and I have a lot in common, from being bilingual to working in creative fields. Fitness, however, is the one thing we've always approached differently during our nearly 17-year marriage.I've been working out since I was a teenager. Now I'm in my 60s and strength train for two hours three times per week, walk our dog daily, practice yoga three times per week, and train for the occasional 5K race.My husband didn't start exercising until he was well into his 40s. Now, at 61, he goes to the gym three times per week, finishing each session in less than 30 minutes. I feel like he could do more, but he's content with his routine.He's supported me as I've trained for a half-marathon and several shorter races, become a certified yoga instructor, and learned to do pull-ups. That said, he doesn't share (or completely understand) my desire to accomplish intense fitness goals. To him, my lengthy workouts seem excessive, but to me, they're a nonnegotiable part of who I am.Early in our relationship, I tried to push my fitness-couple fantasy — but we've since accepted our differences
