In hotel room, 3 rounds of the following PPUSA workout I just came up with:
15 decline push-ups
50 mountain climbers
5 turkish get-ups with a gallon of bottled water each arm
1 minute chair step-ups
1 minute plank
30 seconds arm swings with gallon of water each arm
DONE...right on time for kick-off band, no more time for anything else...
Next day, invert the work-out, same deal.
Way more efficient than making time to go to a filthy gym (LA Fitness sucks BTW), looking for the other 50-lb dumbbell that someone did not have the decency to put in its rightful place (I am telling you, LA Fitness sucks), taking more time than you intended to while doing inefficient cardio, coming back to the hotel to take a shower, etc, etc. All while being nervous you are going to miss one ounce of the festivities. Unless you are a bodybuilder of course and then by all means, go to LA Fitness.
PS: In Cancun, switch a couple of exercises and get your 20 minutes of exercise in the hotel room before the beach, so your wife sees you all pumped up as well. Two, 3, 4 birds with one stone.
