Awesome squatting Ravi. Daft question: Could you not use the same bar that is used for squats for the bench? In my gym, there are 4 olympic bars that can be used for anything.
If not, all you can do is consistently hit 400 and work on getting doubles, triples etc. which I know you will get some time in the near future.
No excuses, just results.
Getting it done one session at a time.
