thanks for your reply swanso5 but can you explain your comment about ditching isolation exercises as i thought isolation exercises were great for building muscle????

sorry if i didnt fully explain myself, i am working out regularly and cover all major muscle groups equally using both compound and isolation exercises and all i was after really was any feedback on giving arms a boost for the upcoming holiday in feb.

is this possible??? i am going to cuba for 2 weeks in february and would like bigger guns, i have a wide array of dumbells and would like some advice to get the best out of arms in this short time
Please help
