It's a modified take on the Ab-Ripper X. Increase repetitions once you feel comfortable with the routine. The duration of the routine depends on your level of fitness (not everyone will finish under 18 minutes) , go at your own speed but don't hold back, be consistent with the flow. You can do this routine twice a week or as much as you'd like once you get the flow of it.
