you can ride with a club/friends at any time of day, any season of the year, anywhere in the world.
still not a perfect solution, since startup costs are required, but if you've got a bike and can swing a smart trainer, it's pretty awesome.
This is objectively not true for me and nearly all of my friends who lift/run/swim/bike/etc.
Physical activity feels good [see OP].
And/or you feel better having done it.
My cyclist friends love exercise for its own sake. My judo friends mostly accept it for what it enables them to do. My board game friends tolerate it, at most.
But if you ask people if they like walking around a cute downtown full of little shops, or surfing, or exploring a valley looking for wildflowers, or going to a nightclub and dancing, gardening, etc., then you'll discover a world of activities that are physical and also enjoyable.
I don't know how true this is. When folks talk about things like a "runners high", an activity that even at my most fit was abject misery, I have to wonder just how differently we're experiencing these things. When I was lifting heavy, I also suffered from some pretty serious delayed onset muscle soreness. I know for a fact folks have varied experiences and tolerances for that. Some people's muscles recover much more quickly from heavy exercise, reducing the overall unpleasantness associated with exercise. With all of the variables and testimony from folks I've worked out with, I have to assume a decent amount of people who exercise regularly actually enjoy the exercise itself. For me it never became more than a means to an end. It's something I know is good for mind and body, but my mind and body consistently rebel against it.
I keep kicking myself for not being more willing to exercise, but I've also recently discovered that my body severely overreacts to stress, even what should be eu-stress, not dis-stress. For example, massage therapy aggravates my muscles and leaves my body more tense and less resilient. I finally started making progress on healing some physical anomalies only after I stopped the recommended massage therapy.
It's made me realize maybe I'll have better luck with "strolling" than "going for a walk," or making up interpretive dances to smooth music than "dancing" to up-tempo beats. Perhaps I just need much more movement, but a lot less intensity than most people.
After 9 months of sticking to it, I found myself enjoying it while doing it.
I had to use a personal trainer to get to that point though, due to how much I hated it initially.
Or you can find an activity that you enjoy but that is also exercise. But then you need someone or maybe a team to do it with and a lot of them are seasonal like cycling, tennis etc.
I've noticed that both indoor rock climbing and bjj have gotten really popular in cities in the last decade and I think this is basically why. Active indoor activities that are enjoyable for a lot of people.
