When doing a routine at this intensity I assume its not ideal for a 5-10week program; However, I see in some articles it is common to utilize this routine for 7-9 weeks. As the routine is designed to utilize more intensity while keeping the amount of workouts needed to a minimal. (Maybe 3 to 4 exercises in a daily routine with around 3/4 days a week of training, seems to be common amongst online articles.) And also the exercises are not to target one muscle group in fact in each routine I browsed through it seemed common to have a bench press, squat, and rows! Im sure its common to use more target muscle isolation like bench, DB press, Decline Press yet over-all in my browsing 5x5 routines seem slightly chaotic (perhaps just coincidence on my behalf for aricles I clicked on). Sorry for not sourcing them too!I have a total biased view of 5x5 as I routinely train one - no more than two muscles a day at the gym. So in no way am I trying to question the methodology behind the program. For years now, in fact other than experimenting with a few split-routines my whole bodybuilding career has been isolation training I never ended up on a serious 5x5 program. I will say I have isolated the muscle with 5x5 technique through-out playing with reps and weight, but never my whole routine, and never so drastic as 7-9 weeks continuous. My question is:If this is a 7-9 week program would it not be a good idea to also add minor isolation exercise to each muscle group? It seems different 3/4 workouts surrounding each 5x5 program are core lifts or exercises designed for mass (bench, squat, deadlift, military press, barbell curls) so to me it just seems to neglect the demand each muscle needs to grow with full definition/shape. I understand that training legs makes your arms bigger ext.. due to the release of hormones. I guess im just not sold, that is all it takes to get each muscle to “take-shape”.
