I like many, have a slight dilemma. I can't seem to shake that extra little fat from my abs. My diet is spot on, so that is not an issue. I have been doing cardio 5 days a week. 3 days of HIIT (usually a spin class) after weights, and 2 days low intensity on a stairmaster. If I was to add a couple of low intensity sessions in the evening do you think it would help? Or am I just going to be overdoing it, and possibly increase my caloric needs?
