Hi all! When I look at everyone else's exercise regimen, cardio seems to involve several different forms for most people. I'm in kind of the unlucky position of not having the financial means to afford a gym membership until I go back to school in September and I can use my school's facilities. I am living in a city without a car as of yesterday and today alone I walked at least 7 miles simply by living a mile away from the nearest subway stop (and having a boyfriend across the city so I have to take the subway), going grocery shopping (the nearest grocery store is a mile away), and seeing how long it would take me to get to my internship (a mile and a half away). I walk briskly but due to a past ankle injury, it is hard for me to move too fast and impossible for me to run. The injury normally does not disrupt my life but would require surgery to correct according to my doctor and that is just something that I cannot do due to current circumstances (living alone in a city and 100% reliance on my feet as transportation).
I try to get in general kinesthetics like push ups, lunges, and squats in for at least a half an hour every other day on top of my walking and plan on going on more extended walks when I have more time on weekends. I am just concerned that by doing only one form of cardio, it's hurting me? Are my fears unfounded?
