One day i do Bi's and Tri's, and the next day i do Chest, Shoulders, and Abs.  People tell me that i should get more rest in-between workouts, but i don't feel any pain after a days rest.  Is this something I should change?

Bi's/Tri's

Biceps-

35lb hammer curls 3 sets (x20)

35lb alternating curls 3 sets (x20)

30lb incline curls 3 sets (x10)

Triceps-
