I remember 13 press ups (no time limit), ~30 sit ups in under a minute.
For the run I think it was 1&1/2 miles in around 10 minutes being acceptable for the middle fitness group.
For the bleep test it all depended on your sex & age.
One thing most people didn't know about was the swimming test (especially important for aircrew). That was 6 o r8 lengths of the pool and treading water for a minute
All of it is easily done if you are reasonably fit.
