I did it. I stayed under my calorie limit (2500) and did 1 and 1/2 hours on the treadmill at 3mph. I changed up the routine though, by raising and lowering the incline function sproadically. I've read that that sort of cardio workout is actually more effective. I don't know for sure, but I was more interested and the time went by faster. My legs are killing me for sure though. I do feel motivated and am looking forward to tomorrow as I'm going to start with my ab-roller. It came with a video that I know by heart, and plan on doing the "5 minute workout" (really quite effective actually) 3 times tomorrow.
Thanks for checking in and please, check back often.
