yhou can def. do more sets, no offense to the other guy, but one thing that ive experienced is to tkae advantage of being on and training!!! for larger groups, bump the sets to 15 or so, and for the smaller ones, set them around 12 sets and eat to grow, not TO MAINTAIN!! watch the carbs, very high prtein and moderate fats, high in healthy fats. keep the reps 8-12, occiasionally going heavy but for the most part, stay in 8-10!!! you should grow and enjoy
