I had read in prof. arshad's book that body building isnt an aerobic exercise. 

how it could be???

i do work outs for muscle gain. so far i have not seen a huge change. may be it is due to my diet. in summer one's appetite reduces.

so please advice me how i should take my diet so that i start seening gains.

2ndly i have read that fish oil is a protein supplement. is it true??? can i use fish oil capsules in my diet??? plz suggest a good and safe diet supplement.

thanx.
