In addition to the intense workouts from Cathe that I have loved for the last 14 years, I've become a huge Insanity fan, too! I would almost say I enjoy the insanity! Enjoy??? Not sure that's the right word. That's like saying I enjoy Cathe's low ends! They burn so good, right? hehe. In addition to the Insanity workout, I'll usually do something with Cathe, too for an additional 20-40 mins, whether it be additional cardio or some weight training. Because of this, I think I'm shocking my body because not only have I not lost any weight, the scale was up 4 lbs this morning. Anyone have any insight into this? Maybe my body is in starvation mode and not pulling from my fat stores and actually conserving them or adding to them?? Do I need to increase my caloric intake? About one year ago I cut my calories down to 1500/day and have since lost 42lbs. I would like to lose an additional 10lbs, so about a 4 weeks ago, I added Insanity to my workouts and increased my workout time from 60 mins to 75-90 mins. I have read about zig zagging my calories by increasing my calorie intake for 3 or 4 days to around 2000 and then doing 1500 the other days. I did this for one week, essentially 3 days and like I said, number on the scale is up. I'm at a loss and a bit frustrated.
