The problem with your question is that yes, your workout is, in fact, involved: the reason being that to get the most effective mass gain, you don't tend to work out "biceps" one day, "calves" the next, et cetera. The best programs for packing on mass tend to involve lots of work with
compound movements, especially the squat, deadlift, and bench press. In other words, while there is probably no harm done by doing a set of preacher curls one day and a set of calf lifts the next day, you're impeding your own progress by restricting your workout to isolation movements.
So, with that in mind... what
is your workout?
