Work Out 6 (Shoulders, Biceps, and Triceps)

I made some decent gains in everything except my second set of shoulders. I really was trying to make a rep gain and think I might have exhausted myself on the first set. However, besides that I think I had a great workout. Here's how I did:

Free Weight Shoulder Press
W) 6 x 22.5 lbs.
1) 10 x 37.5 lbs.
2) 5 x 37.5 lbs. (good weight)

Dips
1) 13
2) 10 (3 neg.)

Push Downs
1) 9 x 50 lbs.
2) 6 x 50 lbs.

Straight Bar Curls
1) 10 x 60 lbs.
2) 9 x 60 lbs. (go up to 65 lbs.)
