Hi ChirpyKez,
A long time since I joined up, 1966, but I was given a full medical, to make sure I was fit enough, no exercises, that came in Basic Training, where you could still be disqualified if at the end, or during, for whatever reason, you didn't make the grade.
I would doubt very much if you would be expected to do the exercises you describe, but if johnlambert, (4GS) is around, he's more recent than me, i'd be interested to know myself.
Sorry I couldn't be more help.
