The article I posted basically posits that for fatloss, shorter but more intense cardio sessions are preferable - check the Fatloss forum if you're interested, there's a lot of info about HIIT: high-intensity interval training. I personally use a very simple program - that's posted there - featuring lots of 400m sprints, and it works fine. As far as diet goes, it really depends on what kind of training you're doing, but you definitely can't let your carbs fall too low. I saw your other thread, and IK is absolutely right - 1900/2000 cals is too low for 190 lbs. Her advice is spot on there and I don't want to add anything to that since she knows more than I do about that stuff.

I don't know how much and how long you've been working to cut, but it's definitely an eventual process, so I'd just up your cals to where your body won't be likely to fight you on the cut, do more intense cardio or interval training, and keep your diet on the right track.

Good luck.
