I said I was 220, not the 242 I should have been. I was in my early 30s. You didn't mention your age, and if you're in your 50s, you probably have no reason to be any heavier than about 200, especially since you're not doing the program anyway.
When it becomes necessary. This is what we call "highly individualized." Try the longer schedule and see.
I don't like it, but if you do and it helps, fine with me.
