I just started this. As in, just got finished with Chest&Back. What in the fuck, I'm supposed to do Ab-Ripper X today as well?! Oh lordy! I can barely walk, I feel sick to my stomach, and feel as if I ran a marathon.
And to top it all off, I could barely keep up with anything on the Chest & back, even pausing for breaks. I knew I was totally out of shape and a fatbody, but christ. I'm 6'2", 215 lbs. so I guess I'm not that bad, but I have a 38" wasteline and basically sit in a chair 80% of the day.
Ok, I'm gonna catch my breath for about 30 minutes or so and go try to fumble my way through Ab-Ripper.
On the pull-ups, I was using a pull-up bar mounted on a door, and since I'm so tall, I couldn't really use a chair, at least not under me. So what I did was move it away from me, rest both feet on it, and do modified pull-ups that way, and even then I couldn't get my bulk over up high enough to get my chin over the bar.
Edit: Just finished Ab-Ripper X. Sick to my stomach big time. I could hang with some of the exercises (not on reps, obviously), but I'll be damned if I can't lie completely flat on my back and do a sit up properly. Could be because of my gut or being out of shape, or both.
