declaredbeauty - did you decide to give it a go? starlux - I love Jillian's 30 day shred - this is that but (believe it or not) harder - I am planning on doing this for 60 days and then going back to Jillian's 30 day shred for maintenance. Jillian is still my favorite trainer but this guy is kicking my a$$. This program definitely does not start off easier - each day it begins with the same warm-up (which is my only gripe so far, that the warm up is the same) - and you are DRIPPING by the end of the warm up, and then he does a really great deep stretch. Then it is another 25 minutes of pure torture. What is nuts is as hard as these workouts are - I'm on day 6 and I am not even close to doing the whole thing, I'm constantly taking breaks, and my goal is that by the end of the first month to make it all the way through - but what is crazy is that the 40 minute workouts of month 1 become 60 minute workouts of month 2. It is really difficult - but I'm loving it and seeing results in a week !
