Well I have a nine month old. I've struggled with my weight for 10 years (since I had my first!) and I'm trying to get if off. I'm using my fitness pal app, just trying to lose 5 pounds a month (for 10 months, lol). hIIT stands for high intensity interval training. Research shows you get as much benefit from a 10 minute HIIT season as you do from an hour of moderate cardio. Guess I'm trying to fast track bc I'm LAZY. I have 5 sons and my oldest is 10, youngest is 9 months so its now or never if I'm going to keep up with these boys!
