Strength should be your primary goal. More strength equals more muscle. I don't see too many jacked people doing pumping routines.
If you want to gain muscle then you must get stronger. Diet will take care of the fat on your body.
Even the ACSM distinguishes between differences in training for hypertrophy and strength. Are you saying there's no difference in training for hypertrophy versus strength? If not, why would I focus on strength instead?
