I speed walk everynight after working out at the gym for 45 minutes. I speed walk the trails everyday, I have just begun speed walking for three minutes then running for one. I want to get up to, just being able to run.
I find it so much better to do the trails, they have hills and I feel it in my legs, much more then doing the tread at the gym. But on rainy days, it's the tread of course.
I also didn't do the running part due to my size D's which are a small c now..LOL I was so worried about people seeing them bounce, so to speak. But "Hanes" has a good sports bra. Although I feel like I have one huge boob while wearing them but, it's much better then "knocking yourself out" while running.
