I would say major overhaul every 3 months. I also may change it from workout to workout. Meaning, if one day I feel like including or discluding something I do.

Bump. Cmon guys......get your asses out of the convo lounge for once and lets talk about BODYBUILDING related matters on a bodybuilding website.

Everytime I train a muscle group. Hands down

for me..i'm always changin things..for me keepin my muscles guessin what works for me....heavy sets one week,rest pause the next week,drop sets the next and so on......try to find what works for you

typically i'd work in blocks of anywhere between 4-8 weeks. by blocks i mean alternating between a similar layout but with different rep ranges, high reps then low and so on. but i'd probably change to a different layout altogether maybe once or maximum twice a year, and that too out of necessity - personal reasons like when or how much time i can spend in the gym.
