Arms and Shoulders

Today is arms and shoulders, my arms still kill from mondays chest and back but determined to keep going, only thing is i think the resistance bands i got are lame so i found some 50kg dumbbells in argos reduced to 34.99 so going to pick those up today and push back my workout to later tonight, not only will i have more time but think it will be easier to follow along and feel it, rather than the bands which do work but i don't feel like they are as  tough as it would be with free weights.
