Not sure if you can do it, but getting some gymnastics rings will open up a bunch of very effective body weight exercises. If you've never tried a dip on rings, its humblingly harder than on fixed bars. The rings and straps aren't that expensive, but you need a place to hang them. Even if not in your room, if there is an area you have access like over the top bar of a swing set at playground works. See https://fitnessfaqs.com/product/body-by-rings/ https://fitnessfaqs.com/product/body-by-rings/ for workouts. Another is parallets. These aren't that big and can be used for calesthenics training like planche. These are great, but it depends on the kind of strength and physique your aiming for.
