thanks for the replies so far.
i don't wanna take some time off. right now, i'm gaining mass better than ever, and that's what i mainly want. if you believe it or not, in the last 5 weeks, i gained 2-4lbs every week, i swear the god. and i won't take off as long as this goes on.
but, i don't know which muscles are growing. i know for sure that my large muscle groups are growing (legs, lower back, pecs). i can see it and i also gained a lot of strength with those.
but i can't really tell whether my small muscle groups grew or not. i did have real good strength increases in the beginning with those and i'm pretty sure they grew in the beginning, but it seems to cap somehow now.
i like my mass gains atm, but i'm not really happy because it seems like my most important parts (bi and tri) are not really growing.
so, what shall i do now?
i don't think i have to change anything in my large muscle group routine, do i? i do an rp set (3 times to failure), and i constantly gain strength and mass. so i'm not overtraining, right?
but what shall i do with bi and tri? really lower the volume to 1 straight set each and see how this works? ok, i know that might be the best idea, BUT i just don't feel like i do enough if i only do 1 straight set. is that really enough to even be able to gain some mass on a muscle by just doing 1 straight set?
oh, and btw, how many reps should i do in 1 straight set? 12-15? or rather 6-8?
