You could also use grippers which has been suggested which also works your forearms or buy a giroball which works really well. See how they go.

The PTI (dont know if he still it one) Paul 'Dixie' Dean holds the current world record for press-ups in one minute. Im not if sure thats still standing lads??
I saw that in the 'Royal Marines Commando' recruitment book i was given when i was 16 by a huge corporal (back then he was!) down at the AFCO nicknamed 'Gaz'.
The record he set was absolutely intense - 116
