Is it to many sets?
 

I do twelve sets per muscle group. Bi,back,tri,chest,shoulder ,neck. Is that to many sets if i split themup into six sets twice a week?

Thats way to much for triceps, biceps and shoulders
For me thats way too much for chest, back and legs as well!

I do 3 sets maybe 4(depending on muscle group) per body part, per week.

What does your normal training routine look like?

I do my workout based on my work schedule. i work rotating shift for a pipeline company so i get a small workout there.Here is my workout. Mon- chest/tri/shoul 6 sets 10 reps each,Tues-back /bi/neck 6 sets 10 reps each,Wend- 12 sets legs ,thurs and fri rest. SAT-chest/tr/should 6 sets 10 reps.Sun back/bi/neck 6 sets 10 reps .Monand tues rest.Wend Twelve sets legs. Start all over again .

What are your goals, do you train for fitness, bodybuilding or strength?
If you're training as a bodybuilder then it is too much both in sets and reps

The only time i like to do higher sets in the 12 range, is when i cut. Bulk go low. It works for me, and im sure other will chime in.
