I'll come back to fail you later Jufes as I'm all out for the day.

Yes I like those arm curl isolators. They work awesome. It's like doing a preacher curl but you do it standing up. You really really feel it if you use it properly. Arnold used to use it a lot. If you don't have one however you can simply do Incline Curls and it will have the same effect more or less.

Berz out.
