When you combine bike and pedestrian hostile cities with the extreme fitness image many have, which requires drives to the gym, excercise becomes that much more difficult to achieve daily.
Some people I've talked to seem to think exercising as much as I do requires superhuman willpower. The opposite is true in this case. It's much easier to get exercise if it's an unavoidable part of your day. I don't own a car, so cycling just happens on its own. If I need a car or truck I can easily rent one. Even in the bike-hostile US one can plan to make this lifestyle possible.
After that I play a few VR games that are full body/active type stuff (room-scale). For example, Space Pirate Trainer is my current jam; I currently hold the #3 spot on the world leader board and my games of late tend to take around 45m from level 1 to 70+. My heart-rate btw routinely hits around 130-140 toward the end of one of those game.
Extreme stuff is awesome too if you are trying to maintain a high level of fitness for specific needs but most people can get by with way less and have pretty excellent results in day-to-day wellness. Tabata, burpees, pull-ups all have their place but even those you can do much less frequently than most think and benefit hugely.
If you always overdo it, it will not stick. And continuity is the most important part.
