Yes, thanks! Have the book, so saw that as well. But this seems for leg-only bikes, was interested if there were any new thoughts on airbikes given the new (relative to publishing date of the book) popularity with the tactical/crossfit communities as well as the demands on the upper body. Pretty challenging to use an airbike without a saddle. Curious if any of the coaches had worked them into their training regimens for their athletes.
Thanks!
