Are there any good bare-bones cardio workouts I can do while staying off an injured foot?
I've got a tendon injury in my left foot that makes it painful to walk, run, or do much that involves flexing/putting weight on it in any significant manner. I've tried foregoing the cardio portion of my exercise for a couple of weeks, and had the inflammation recede, but it always comes back once I start again, so I assume I'm not giving it enough time to heal.
I usually either jog or run stairs to get my requisite cardio in, but now this exacerbates the injury. Is there an alternate cardio workout that can be done in which the injured area can be avoided?
The twist: I don't have access to a gym, pool, bicycle, or any manner of specialised equipment. Basically just a balance ball and whatever you'd find in your standard apartment. (Hence my question; I've seen these threads
, but the former doesn't address cardio specifically, and the latter focuses mostly on swimming as an alternate activity.)
