Yooo js you don't need any equipment at all
I used to fuss over equipment costs but instead I've just been working out equipmentless at home, there's a ton you can do (pushups, crunches, tricep dips, planks, squats, lunges just to name a few) without needing anything other than maybe a chair or bed to prop yourself on. Just look up equipmentless workouts and you'll probably find one that'd work for you. If you want weights you could also use water bottles!
