(Hi Randi & Kathy!)...
I've been doing it since the beginning and am REALLY enjoying the cardio/weights split. I've been eager to concentrate more on weight work than cardio, to see what it does for my stuck weight. So this is great. And I just love that when I feel "tired of the cardio" , the weight segments pop up!
I definitely feel more defined muscle wise. Not sure if I'll see a weight loss, because of the muscle gain, now, so I will gage it by how my clothes fit...
I would'nt say my appetite has increased. I'd say it's about the same. I eat every 2-3 hours during the day, and try to get in protein with every mini-meal. Moreso with this rotation. I still have an "appetite" , rotation or not though (probably more emotional than physical).
I'd say jump in and DO IT! It's great!
