Well, if that is your routine and you get results from it then God bless you.

It looks as if you are overtraining your arms. Read the beginner's thread. Muscles need time to recover. Including abs.

I think that if you are doing 100+ reps that you are using a weight that is too light. And if you are at a gym, you are probably making the people waiting for the machine very angry. LOL.

Also, what are your goals?
