I live in the desert where going outside in the summer is intolerable. What's helping me immensely while working from home is playing some VR games throughout the day. If I want something light I play a few rounds of archery in Holopoint. If I want to max my heart rate very quickly I'll do boxing in Thrill of the Fight.

When I visited Houston I felt like I was being held hostage. I love living in a city because it makes it really easy to be active. Time spent in Houston feels like it's being spent in the most hostile suburb on the planet.

Honestly, I think Houston might actually be hell.

I highly recommend doing a basic weightlifting program. I find lifting weights, and the goal setting/tracking involved, to be much more engaging than cardio exercises.

If you don't have access to weights, get a pull-up bar and some pushup handles.

I saw a huge improvement to my overall health and physique doing a basic pull-up and pushup program.

I have a membership to the local YMCA, but only have an opportunity to go once a week since I live in your typical unwalkable/no-public-transit suburban area and don't have a drivers license. Used to go a couple nights a week when my daughter still napped and stayed up until 9PM since we could go as a family and have dinner afterward, but now she's in bed by 7:30/8:00 and there isn't enough time.

Another year or two and things will be looking different again, for the moment getting some exercise on a daily basis is still a better spot than where I'm at.

Invest in a $20 pullup bar. Every time you pass it try to bang out a few reps.

I went from doing 10 pushups, no pullups to being able to bang out 100+ pushpus and 50+ pullups over the course of a day.

I can now do prob 50+ pushups and 10+ pullups in one set. Took me less than a year to get here.

I was the kid in MS/HS that coudn't even do one pullup!

If it's practical for you, consider getting a dog. Dogs need to be exercised every day so it forces you to get out and walk or run at least a couple miles every day. And by "dog" I mean a real dog, not some fragile inbred abomination that can't handle a run around the block.

And don't have a yard, or if you do, don't allow letting the dog into the yard be a stand in for taking the dog for a walk. Obviously that defeats the point for you, but it also doesn't do the dog any favours either.

My large inbred abomination (Bernese Mountain Dog, cute, cuddly, overbred) has never lived anywhere with a yard, so gets real walks.

My wife and daughter would love a dog, but we rent and already have a couple cats so it's not really in the cards right now (the cats alone aren't an issue, but trying to get the OK from the landlady for another animal isn't in the cards).
