Here's a link to SP's upper body exercise demos:

s.asp?exercise_type=upper If you have excess fat to lose in your arms, that will be achieved through a healthy diet and regular exercise. You can't do exercises to target fat loss to specific areas.
Also, don't be afraid to lift a weight that's challenging and fatigues your muscles in 8-12 repetitions, 1-3 sets.
Hope that helps,
