I don’t have a favorite, but there are several that I could not maintain health and sanity without, including: hiking, yoga, calisthenics, taiji / qigong, free movement, and at least one cardio (I currently swim and run.) I’m currently struggling with juggling.

With lazy mazy motion the fish slips through its watery world. With no apparent purpose but to trace out a route through dreamland.
What is your favorite form of physical exercise?
I play no favorites. I love calisthenics, yogasana, running, swimming, functional movement, movement drills (e.g. martial arts,) etc.
I do have least favorites though, and – collectively – those are exercises where I have to go somewhere in particular to have access to some specialized equipment. So, for example, I don’t care for weight lifting or using ellipticals or climbers, etc. (I still enjoy the exercise well enough, but it’s more hassle than it needs to be.)
My whole equipment inventory consists of a yoga mat, a pull-up / dip apparatus, and a few resistance bands, and I can make do without those quite nicely — e.g. when traveling.
