My routine is 10 minutes cross trainer, 10 minutes on the bike, some stretches, and then about 30 minutes on the weights, then I reckon about ten mins floor work. Then if I have time head for a swim.
I change my routine every couple of months.
that could be fantastic or it could be very poor, depending on what your goals are

plus it's something to do right? Get some choons on and you're away.
I know a few PTs who're very into their BB work, so maybe my view is a little skewed.
