I suggest you set aside an hour or two every night (in fact, it's best to practice after dinner, so you won't get fat easily). You can find a high table or something like leg press, a chair, you can do body exercises or leg stretching exercises, you can do handstand exercises against an empty wall, and if the living room is spacious, you can do bending and forking exercises (prepare a soft and thick cloth so that you won't hurt yourself easily, and in addition, you can find a high cabinet so that you can practice hanging your waist. If you want to press your knees, find someone who weighs more than you and sit on your knees (provided that you sit on the ground with your legs straight, and spread your feet if you can stand the pain).
