Arnold's chest routine

The chest muscle is one of the main Arnold's strong points that we all wish to have the same.
You can notice his chest from different angels & many poses he created. He made his amazing chest by working out very hard & not by only wishing.

So lets mention the training routine he followed:

1. Incline Bar press
2. Flat Bar press
3. Flat Dumbbell flys 
4. Dips
5. Cable cross (with straight back)
6. Pull overs.

So the above exercises are the standard routine he followed during his career.

Best of luck
