I haven't been to class yet, but my wife and I are a study in how jet lag completely discombobulates someone. Neither of us can stay asleep for more than four hours because our clocks are so far off. It's waking up at 4 or 3 in the morning and not being able to get back to sleep.
In an attempt to stay in some kind of shape I tried to keep up with Pat's challenge of 100 push ups just to see if I could do it. Bob at Striking Thoughts has broken it up to 50, rest, 25, rest and 25. I figured since Bob and I are roughly the same age I could do the same. I thought wrong! I guess heavy lifting doesn't translate to quantity. My best on the trip was 42, rest, and 10. I was too fried after that to do more. Yesterday at the gym I was able to do 50 in one shot, but nothing more.
I'll continue to try more in my morning warm ups and see how far I get.
