You are "kool" man, I wish my husband of 35 years was as enthusiastic as you. He is 10 years older than I am, but there is no time like the present to get active! He is always giving me excuses why he can't do this or that, or I'll do such and such later; then never does. Oh and THEN when I tell him you said you would do..., he gets mad at ME!
Feeling exhausted and depressed!

Yeah, that's what happens when we're married and we get TOO comfortable! The thought process is: I gotta exercise to look good to attract a mate to get married. Then, once we're married, the thought process is: I've already attracted a mate, I'm already married, what do I need to exercise for? The answer is: FOR OUR HEALTH! To FEEL good!

We don't do any physical activities because we are both sick.
However, I tracked my Walking at work and it appears that I walk an equivalent of 5 miles per day

I agree Koolman, it's great having a partner who enjoys being active, enjoys the same activities and does it with you.

Not all people who are comfortable in a relationship give up on exercise and staying in shape though, I never did.

I didn't stay physically active to attract a partner (or to keep a partner), I always did it for me, my own physical and emotional well-being and I've been active as far back as I can remember. Both my parents were always very active and it's how I was brought up. Staying active comes as natural to me as breathing does.

When I broke my leg a few years ago and couldn't do much of anything for 8 weeks, it was hell for me.

My mom who just turned 87 walked 3 miles every day around the park with her dog (weather permitting) and she went to the gym 3 times a week until she got sick (cancer) last August and could no longer do it.

Sorry to hear about your mom Leather.

I have always been very active too.

I do Cross Fit 4 times a week and now that the weather is getting nicer I am roller blading and biking.

My Bf is getting a bike so we can ride together this summer!
Yay!!!

No partner here, but recently was able to bring my dog to live with me again, so at least a short walk per day is mandatory.

Healthy-active is something that sometimes I find hard to balance, when I was younger I suffered eating dissorders and used to work out 4 hours with no more fuel that one small meal every day, so I have to be careful so I dont go back to unhealthy-obsessed-active.

But I find it hard to even find friends who'll join me for just a walk at the park at night so just me and the fur baby, we don't mind though.

I have been working out at gym with my partner, and I don't really like working out but like the feeling of getting job done, I like swimming, however current partner at moment cannot swim. I love kayaking/paddle boarding and anything with water.

My SO is a work out junkie. It started well in to our relationship. I am not. I don't hate myself for being bigger. I don't rely on my size to attract people to me. I'm not unhealthy. So he goes to the gym with his friend. They work out together and he and I don't talk about it. I like to walk, often for hours, and aimlessly. He hates that. I tried working out with him once, I couldn't. Because he 'encouraged' me so much that I felt like a failure and he ended up getting mad when I couldn't do what he felt I should be able to. So we do other things together instead. That's what works for us.

Walking, swimming, kayaking/paddle boarding, spin classes...these are all activities, people and you should feel proud for doing them! They're great exercise! You don't have to kill yourselves with weights to be healthy!

Great point Koolman.

Just stay active anyway you can.

I love to Kayak, hike and walk, and periodically go cycling.
I am also having the toughest time finding a man my age who can keep up with me energy wise. It seems like so many men who reach their mid to late 50s start to become old in their minds, or else maybe they are not so good at eating healthily, and so they genuinely do not have the energy.
I walk on average about 12 to 14 miles during each week spread over Monday to Friday, and love to spend large chunks of my weekends outdoors doing something physical like hiking or kayaking.
I try to eat a really healthy diet and it pays huge dividends energy wise. I just don't understand why more people don't see the benefit of it, because they love complaining about how little energy they have, or how many aches and pains they have, but don't try to help themselves.

They're set in their ways and refuse to.change those old, bad habits.

I just modified my diet to greatly reduce carbs in lieu of protein. The gut is shrinking and the energy is improving!

I work out to PX90 every morning, I think Tony and I have a thing going..(he is on the tape and funny) My husband worked out with weights all the time until he got ill. He'd spot for me and I him, doubt I could have helped him much if he started to drop the bar but I was there. Totally enjoyed the time together and so miss it. We had the garage set up as our gym, but I moved all the equipment to one side so I could park my camaro in the garage too. Now am alone and miss having my partner working out with me. The feeling you get after you work out is awesome..Better then any drugs!

I like to bike ride also. We have the most amazing trails in the area where I live. I am now divorced, but while married, my husband did not want to join me on the trails. Since I don't feel safe out there alone, I joined a few meetup groups that go for organized rides in my area.

I'd say it doesn't have to be your potential partner that enjoys those pastimes with you. I understand it would be nice, but you may find a perfectly compatible partner, who doesn't happen to enjoy those two hobbies. So why not join up with a group that is into biking and going on organized rides? Or just bring the subjects up with casual acquaintances and if they have similar interest, suggest doing it together. Meanwhile, you will be making more connections and have a better chance of coming across Ms. Right. She might be a friend of theirs or someone you bump into when stopping for a smoothie.
