Biceps Sore After Pec Dec, Not After a Biceps Day?

Thats the problem, my biceps get hit with back, biceps day, and also when I do chest because of the peck deck. I may have to just stop it because the soreness is annoying during other workouts involving them.

And to WOOT, I hate starting anatomy/kinesiology arguments, but the long head of the biceps is a shoulder flexor and will definitely be worked in horizontal adduction due to the angle of pull. That is not its main function, but a function nonetheless.[/quote]

Are you just doing pec deck as the last movement on your chest day?

Have you tried dumbbell flies as a substitute? cable crossovers?
I like to do high rep Hammer Strength incline bench as a finisher.
You could also try dumbbell flys on a slight incline. Those are nice, and I’ve never felt soreness in my bis from them, whereas I have from the pec deck. Give them a shot.

In the end, the finisher isn’t as important as the heavy pressing you do, but body parts overlapping in soreness isn’t good.
