Hello y'all,
I did a search first because I know this is sort of an elementary question (that I figure will get a variety of answers).
I typically change routines every 4 months or so. The reason I ask is because I was talking to someone at work that says they do a different circuit training split every week...
I was under the impression that you would want to stick with a routine for long enough to build "neural pathways" or some such thing...
So in short...what's a good range of time you should do a routine before changing it up??
