I'm a 16 male and i got to the gym 5 days a week, this is my workout routine for chess/shoulders (i do rest of the body other days), i do 8-10 heavy reps, 3-4 sets. (free weights)

CHESS:
1: Flat Dumb-Bell Chess Press
2: Decline Dumb-bell Chess Press
3: Incline dumb-bell chess press
4: Flat dumb-bell Butterfly’s
5: Incline dumb-bell Butterfly’s
6: Decline dumb-bell Butterfly’s

Cables:
1: Pulleys on ground level. With handles to side hips. Pull in towards chess crossing arms
2: Pulleys over head, on knees. Cross arms then bring arms to sides
3: pulleys shoulder height, butterfly's

1: Dips
2: Flat table Dips

then i finish off with some weight machines:

after this i do a AB workout and leg excercises, normally i run a few miles at the end but due to a hip injury i can't do that for a few weeks.

will i see results with this? should i change something?
