I am in the process of trying to bulk up right now. been working out for about 7 months off and on. am a very hard gainer. typically, mon, wed and fri are full body workouts consisting of squats/deadlifts, bench press, dips, rows, pull ups. If i want to put size on my arms and calves as well is it necessary on the off days to do things like curls, tricep extensions and calve raises or will these things grow as a result of the full body workouts. any advice is appreciated..
