Its the best for naturals, ie no juice, no, eca's, no thyroid meds, no caffeine
and it for endurance and definition NOT a full on BB routine
Day 1 is upper body, I kinda envision the workouts as being like swimming practice when i go in the gym not going for broke, but the workouts are definatly intense
the way I have this set up is so that your body gets maximum recovery, alot stimulation, but alot of frequency too for maximum calorie burn.
Day 1 for example hits chest with back, all head of the deltoids get hit with the pressing and rowing, and the arms get toasted as well, thats why you only have to do one isolation exercise for delts, and arms cus they are already worked hard.
day 2 run outside to keep your cardio vascular system primed, but no so much cardio that it becomes a huge chore, seperate from a leg day.
after a mile and a half you get the heart and lungs pumping, and your legs are ready to go.
you go to the gym and hit the legs and abs with a brief and effecient workout
if you look at an anatomy chart a better a book of gray's anatomy you will realize that every body part is hit.
you could also consider this as "point of flexion" training, if you actually look at the routine you will realize that every plane is worked, with minimial effort
this program is very effecient, and its not for hypertorphy persay, but more for endurance and ultimate definition, while preseving things while going on calorie restriction,
unless you are on AS you can't do conventional BB plans like in Flex unless you got genetics.
Incedently one of the most successful IFBB pros known for his shocking condition, does a full body program every other day like the one above (but obviuosly far more volume and exercises) and his name is Jay Cutler
