Resist the urge to start doing silly shit like handstand pushups, the wrist strain vs potential workout from bodyweight is a garbage tradeoff. I used to enjoy walking on my hands a lot, then I started noticing I'd wake up in the morning and I could just roll them back and forth to produce an audible KRPOP so I stopped doing that so much.
Same with pushups, after a while you're only really getting tiny amounts of muscle building vs joint and tendon stresses because it's easy to trivialize bodyweight for lots of workouts, but you can do stuff like freeweights, pulley resistance, and so forth to go after parts of those muscle groups which just kinda sit around being bored during pushups. Used to have a fairly obvious pigeon-chest so I set about figuring out how to cover it with muscle when I was really young, got normal looking pecs now but I had to move to weights to actually build them out enough to get there since I wasn't heavy enough for pushups to do shit despite doing all the different stances, centered together, way out past shoulder width, above or below my shoulder height, was nice arm work for a while but that don't help with the sternum bumps dammit!
I did get a bit of a noticeable gain for a while when I was doing those uh, the fucking weird marine ones where you go from like a yoga pose with your ass up and legs straight then slide forward like you're going under a low bar and pressing your torso back towards vertical with your hips down low at the end before reversing... can't remember the name, sunrises or sunups or some shit maybe?
Gotta do them slow as you can manage without shaking and it's a pretty awesome exercise to toss in there.
Now I'm happy I can relax and maintain the shit I built up as a nutty kid and teenager.
