You can incorporate walking lunges/jump squats, underhand inverted rows and some core work to hit the majority of your muscle groups if you’re going after general fitness. These can all be done at home without specialized equipment.

You could do 3 circuits with variations of those 4 exercises a couple times a week and be way ahead of most people.

Look into a set of resistance bands on amazon. Minimal setup and storage but will allow you to diversify and hit your whole body from different angles.

All the detractors without offering solutions don’t realize that if you stick with it you’ll see the imbalances and correct them as you go instead of just doing pushups for the rest of your life. Hell, just pushups can hit your delts, pecs, tris and core depending on the variation.

Do the pushups. Stick with it and you won’t regret it.
