The hotel gym has no pull-up bar, no rings, no barbells, no heavy weights. Just a bunch of elliptical machines, stationary bikes and treadmills, along with a few weight machines. Not good.
I ended up doing a bunch of handstand push-ups, some dumbbell bench presses (yes, it's been a while), and some side presses.
"Death by Burpees":
Start a timer and -- with a continuously running clock -- perform one burpee at the start of the first minute, two burpees at the start of the second, three burpees at the start of the third minute, and so on until you can't finish your set of burpees in a minute's time.
Result: I got about halfway through my fourteenth minute/round before time ran out and I collapsed in a sweaty puddle. The first ten rounds seemed remarkably easy, but I suddenly hit a wall in round 12, and quickly went downhill from there.
This was a gut-bustingly fun workout -- and desperately needed after last night's bacchanalia -- but I got some weird looks from the other people in the hotel gym.
