We all know that we can get some good cardiovascular exercise while flying (when we scare ourselves) but i have discovered that we can get good solid documentable exercise while flying.
I had the pleasure of flying my RV10 - 31 hours round trip to SNF. On the way back over the southern states we were getting bounced vigorously around by 40+ knot crosswinds. That evening in the hotel room i just happened to look at my iPhone Health app. It showed that we had walked/ran 4.5 kms and climbed 10 floors !
So there you go, dont go for a boring treadmill session - go flying !!
