we did our fitness championships based upon %-age of body weight.

bench at 75%, curls at %25, and then did max reps within 2 minutes.

then, simply add a mile or 2 mile run or both.
best time wins.

we also added cals, like push-ups and pull-ups.

i like the %-age thing for your bets because it takes
into account that you might be 5'4" and your buddy is 6'10".

What about the increased workload for the 6'10" guy because of his longer limbs, especially for the bench-press?

It's very hard to find a "fair" fitness test. If it's just the motivation you're looking for then pretty much any of these are good.

If you really want to win the prop then the old adage is always true: "The competition is won in the negotiation"
