I do cable tricep extension, close-grip bench press and cable tricep push down (standing up using a lat puldown machine and either a flat bar or rope)
For biceps i do standing curls with an ez bar, seated dumbell curls (dumbells facing foward and behind, not parralell), cable curls and concentration curls.
These are my favourites and have been good for me, i may also use a french press (same as a skull crusher but using a tripcep bar; skull crusher being when you lie on your back with dumbells in your hands and fully extended arms above, and then flex your arms at the elbow, towards your head and then extend them back to the starting position)
