JJ,
To answer your question it really its person specific. What i can suggest to do is to mix up your cardio. These seems to work the best. I suggest that lower intensity cardio be done 3 -4 times a week first thing in the moring and your HIT sessions 2-3 times a week be done on a non work out day and later at night time (5 pm ) Another experiment you may want to do is to keep your diet consistent and do 3 days of HIT training on non workout days and then the following week do the traditional 5 days o low intesity (30-40 mins) first thing in the morning and see what yields the best results. I believe a conclusion you may come to is that the 3 days of HIT (20 minutes) will yield better results then the 5 days of longer slower duration. AS we spoke on saturdday at the contest. By the way i do have photos I can send you and if you need help getting ready just give me a holler and I'll see what I can do to help.
You look great on saturday, I think you may have listen to too many people for last week of prep or you might havegotten confused. Feel free to give me a PM and i'll help you et it right for next time
