Well? Should I?
What I mean is, I train in a fairly similar way to Wendler's 5/3/1: I basically ramp up heavy sets of low reps on my compounds, and go for a 5RM one week, 3RM the next and a 1rm (or 2RM or slightly heavier 3RM depending on how I feel) the week after, with a deload week on the 4th week.
Thing is the heavy compounds cause me the common problem of not adding mass in the places I necessarilly want it. Presses do NOTHING for my arms and squats do NOTHING for my quads. The majority of my strength comes from compounds, but the majority of my GROWTH comes from high rep isolation stuff, most notably curls/extensions, flies and leteral raises.
But should I care about the whole sarcoplasmic vs. myofibrillar (sp?) thing? The reason I ask is because how i understand it is that sarc. hypertrophy is just an increase in fluid in the muscle, and you can actually lose the size quite easily (read that on DeFranco's site i think). The myo. hypertrophy is all about getting stronger, but if I increase my 10RM, haven't I just got stronger despite it being in the sarc. rep range? Personally if I was to try and get bigger using just low reps it'd be a hundred years before I added 10lbs, but I don't want to think I can lose the size I worked so hard for in a matter of seconds...
