Gym Exercise Questions?

Question

Ok, I've been going to the gym quite a while now (half a year) I'm 16 y.o. 6 ft 1 inch, and I'm pretty happy with my results. During these 2 vacation weeks, I m going to change greatly, itll be like taking off the last imperfections. I have some questions however
-when you bench on a decline (http://www.home-gym-direct.com/Images/250x400/Maxicam_Compact_Decline_Bench_Weight_Bench_II.jpg) , which part of the chest works out?
-I was getting my ab packs, but I just stopped doing thsoe cause they were a pain in the butt. Im gonna get em during these two weeks. Iknow abs are a small muscle, you think I could work em out 1 day yes and one day no? I do sit ups on a decline as well, and for the jelly rolls (i dont know the name of those muscles sorry) I've never worked them out but they put a new machine, which I'll use along when im doing abs), and dont worry about the obliques, but I will also do them the days im doing abs.

thanks!

Answer 1

The decline chest press works the lower pec muscles. Just like an incline chest press works the upper pec muscles. Of course, all chest press exercises also work the tricep muscle fairly well also.

Yes, you should not work your abs every day. In fact, many professionals only recommend working each muscle group once per week. The actual muscle growth occurs primarily in the rest time following the workout, so if you workout the same muscle ever day you are actually limiting the growth of that muscle.
