I would advice doing skullcrushers,EZ-Curl bar,5-15 reps pyramiding up in weight and decreasing reps at the sets get heavier.
5 sets,of 15,12,8,5,12
After these,I would do seated French Press.......also using an E-Z Curl bar...........10,8,8,15 reps.
Finish off with Pressdowns for 3 sets of 20,15,and 10 reps again adding weight each set,then do one set of Triceps Dips Between Benches with weight in your lap(plates)............have someone remove the plates and keep going to failure.
If you`re a beginner,just do 4 skullcrusher,and 3 sets of pressdowns,followed by one set of the French Presses for high reps.
