I discovered Tony Horton's P90X Yoga during the lockdown. My wife prefers Sean T's Insanity workouts. The Yoga was low impact to the joints ; insanity was too much for my ankles. Whatever you do, do it slowly and deliberately and make sure you dont pull or sprain something.
I've done some of those high-intensity YouTube videos at home. Here, I'd either have to do them on top of the bed, or do them in the 2 foot space between the bed and the wall, or in the 3x4 foot shower.
The bedroom, toilet, and shower in total area of 8 sq. m. / 86 square feet. That's 8 by 10.5 feet, with a double bed taking up most of it, and a pair of glass walls separating the toilet and shower areas. I haven't measured it, but it's advertised as 8 square m, and looks roughly 8 by 10.5.
