I try to get at least 15 to 20 minutes of exercise at least 5-6 days a week. Step machine, push-ups, ab exercises, and I have also always lived in houses with stairs, so I am constantly running up and down stairs every day, too! I have also always walked quickly (people joke and say I create a breeze when I go by, lol!)
I like exercising to create the endorphin rush - makes me feel better emotionally. Not to mention feel better physically - I find that if I miss a couple of days, I start getting really stiff and feel sluggish....
