Program or not?

Just wondering who follows different training programs and changes them every couple of months. And who changes keeps the compound movements but changes the rest of every session up a bit?

I do. Always do front squats, deadlifts, abs, pullups, push-ups, calf-raises. The rest I change as I feel. I don't vary it as much as the pro's say you should though - prefer routine

I change according to goals and caloric expenditure needs.

I try train every session differently or I would step foot in a gym due to boredom. I might even take old the old Arnold encyclopedia

I like to switch things up every 4 weeks as long as u are progressing even if it's the same exercises in a different order it shocks the body a little, always good to change when u want to keep yourself going otherwise it becomes tedious and mundane
