i really like the idea of isolation moves before the big lifts. This goes against everything that the current routine i'm trying (DC) preaches but it does make sense. Typically i have always done the big compound lifts first and then went to isolation, this makes much more sense in terms of being able to actually work and isolate those muscle groups when doing the big lifts. Stretching is a big part of DC training and i will say even this early in it not only hurts more than the actually lifts you feel awesome throughout the rest of the day and into the next.
