I am relatively new to this cardio thing. Like Jan 1st, 2008 new. I see that HIIT is really popular here. Is it too early for me to start doing HIIT? Should I stick with just 30 minutes on the treadmill 3x a week? I want to lean down.
Just changing my eating habits and exercising, plus two times of 30 minute cardio, has got me down to 238 from 244 since January 1st. Just trying to maximize my time and effort.
