Starting this. Cleared out a spot in the basement (just hope the ceiling is high enough.) I've had trouble sticking with any of this stuff in the past, but I am the heaviest I've ever weighed (270 @ 6'1") and absolutely need to do something about it. So questions:I haven't worked out (officially) in a few years, how bad am I going to hurt myself? (Btw, I did see the doctor for a physical about a month ago, nothing physically preventing me from doing this, in fact, working out and dropping weight was encouraged as my main goal.)Better to do this in the morning or evening? I tend to be a night person, so I could see trying to do it in the evenings, but I get home just in time for dinner, so it would be late evenings. Mornings leave more of a chance I miss them but that probably just falls to self-discipline to get up in time to do it.How critical is the diet portion? Obviously I'm going to be trying to eat better while I do this, but is it imperative to stick to the diet they proscribe, or is just eating better foods enough? (Along with staying away from fast foods, obviously.) Anything I forgot to ask? Help me out.
