what is the theory behind switchin up ur routine (reps/exercises/split/weight) to keep your body guessin? should you do it every so often...say every third week or so or more than that?
let me give you an example using my chest workout
Week 1
Flat BB Bench
Incline BB Bench
Decline BB Bench
Incline DB Flys
Standing Cable Crossovers
Dips
Week 2
Flat DB Bench
Incline DB Bench
Decline DB Bench
Flat Bench Cable Crossovers
Dips
pushups
Would i be better off keepin this routine and switchin up the exercises every week (like i do now) or would it be better to do week 1 workout for a couple of weeks and then do week 2s workout for a week and go back to week 1 for 2 weeks?
any advice is always appreciated
