plateau busting

I'm stuck at a bit of a plateau with most of my training, not all just most. I know it's commonplace to hit plateau's from time to time but this seems to happen quite often (every 4ish weeks), I generally take a week off (or just do completely different stuff and light stuff) that seems to vamp me up again but I don't seem to advance much. Is there any good plateau busting techniques people have had success with?

And Coach Sommer, George was telling me in another post (active rest) about how you advocate a cycle of loading, overloading and underloading? ratios and such?

When I hit plateaus I try to work the little bits, the synergists, and the stabilizing muscles, say I get stuck on bench, I would work decline, incline and dumbbell presses. When I got stuck on tuck planches, I began to work pseudo-planche pushups, diamond push ups and my lower back, and when I got back into tuck planches I noticed advance tuck planches seemed a lot easier and doable.

I don't really take weeks off, unless it is just a stressful week and I don't have time or feel like exercising, try to mix up exercises and not get bored you will notice more gains and you will not become as bored.

for me i think half of gymnastics is flexibility so when i feel overtrained or not feeling that drive to work out i will take a week off and barely exercise, i will stretch everyday and do handstands and basics gymnastics, after that week is over im back and better than ever

You might benefit from George's thread on cycling. It has some good info on ways to avoid the dreaded plateau.

Kbryk gave some good advice as well, sometimes you just have to work the secondary muscles so they can properly support their neighbors.
