Do you always train heavy or go light/heavy weeks???

[goatmon]

I used to train heavy all the time and got no gains in strength (after a few years of this that is) or size and started to get injuries, then I backed off by training heavy 1 rotation (3 on 1 off) and light the next. It works wonders gives me rest and I've gained size and strength since. The injuries are much fewer and I really look forward to the heavy days. I wish I started this years ago, but I haven't used any AAS (yet) which would completly change my routinue.
