I've been doing a lot of reading of old threads here and various online articles and there are arguments both ways for doing "light" days with higher reps every so often. Some say every few weeks, some say every 8 weeks. I really don't know what to believe. Here's the million dollar question: is this NECESSARY, or is it all subjective? I mean, I have no problem doing lighter weight with more reps once through my cycle every blue moon, but if it's not doing anything for me, what's the point? I know some will say it depends on the person, etc, but I want to know what you guys do. What are your honest opinions on this subject? Right now I try my hardest to lift until failure (until I can't possibly do another rep) for 2 sets, of 8-12. Once I can do 2 sets of at least 10, I bump the weight. I'm extremely skeptical of doing, say, 2 sets of 20 with lighter weight. Flame away.
