How much should i do them if i want these muscles to look bigger? I normally will do 10 sets of 12 everytime i go to the gym, should i do more or is this okay?

10 sets of 12 o wow thats way too much, your muscles respond better to low rep heavy lifting, here are some good ranges to choose from:

4 sets 8 reps
5 sets of 5 reps
4 sets of 7 reps

on the final rep of every set make sure that you are lifting to failure ie. you can't do another rep to save your life!

you need to be lifting heavy.

low reps are for people looking to gain strength and muscle, plus i wouldnt just stick to cable exercieszs because after a while your body will adapt to the same routine and you will not see any results.

play around with your weights routine every week, ie, change your exercizes and rep ranges around to shock your muscles. dont let your body adapt to a routine.

Start increasing the weight. Reps = definition / Weight = size.
