Welcome Miez....

Congrats on starting your first challenge!

I do BFL by the book, eating my six meals a day and have really liked it. I'm not sure how your different eating pattern may effect BFL but I know that others do modified LC BFL so I'd say go for it!

As for your cardio.... I think any form of cardio will do the trick as long as it will allow you to do HIIT. I've never used the WATP video so I can't help you there. I do my running on a treadmill and every two minutes I take it up to a run for a full minute. You should be pushing yourself hard by the time you get to the end of your 20-min cardio. I'm usually sweating and gasping for breath.

Stop by my journal anytime if you're looking for inspiration on BFL - the program has done wonders for me!
