I feel skydiving includes a lot of physical training.
Running to the packing tent after landing to give the rig
to the packers and getting another one, running to the plane,
running to the manifest to find out I'm on a five minute call,
packing like hell to make it, running to and from the video
room to edit video, running to find the tandem passenger and
deliver the video in time to get to the next one, etc,
not to mention running for cases of beer :-)
Skydiving is the worlds most exciting way to loose weight!
