Holiday work out routine.

[theeedude]

If you only had a pullup bar and nothing else except floor to work with, in a vacation situation, what would your routine be to stay in shape?
So far I have:
situps: 3x30 for abs
wide grip pullups 3x10 for biceps/back
pushups: 3x20 for triceps/chest

Obviously missing are shoulders, which I would like to do. I don't think I can do head stands, any way to work those in at a resource limited setting?

Squats or pistol (one legged) squats
You can put your feet up against a wall to help with balance for handstand push-ups

Punch/kick a wall - only problem is, walls "don't hit back"

 

[skace]

Weightless squats, bench dips (done off a bed or chair), lunges, leg lifts, lots of variations in situps, pushups and pullups.
