Not really much point maxing out every time as it's counter-productive. What I do every other week on a Saturday is a 'test day'.
This is my training routine:
Circuits = 3 x 45 seconds each of press ups, sit ups & tricep dips - 4 x 1/2 max chin ups - 4 x 15 squats (with 10kg in rucksack) - 4 x 15 lunges (with 10kg in rucksack) - 4 x 45 seconds up & down on a step (with 10kg in rucksack) - 4 x 45 seconds alternate leg raises (lying on the floor) - 4 x 45 seconds dorsal raises.
Test Day = 1.5m warm up run – 1.5m best effort – max press ups in 2 minutes – max sit ups in 2 minutes – max tricep dips in 2 minutes – max chin ups (not in 2 minutes)

Obviously this is only my timetable and it isn’t set in stone. Everybody is different and likes to work to different methods. Whether this will be enough to get me through RT is yet to be seen. Might be good as a general guide though. Obviously, when doing the circuits you won’t want to start out doing 45 seconds of each, maybe best to do (2/3 x ½ max) of each like I mentioned previously.
Like I said though, this is only my timetable and may not be suitable for yourself. I’ve been training for a while now and have built up to this over time. Still building on it even.
Probably gonna get shot down now anyway and be told I’m speaking BS.

Hope it’s of some help mate.
Oh yeah, don’t start trying to run 10m straight off either. You’ll injure yourself big time!
