I am looking for a few excerices that I could do while seated in an airplaine chair. Any change you could add some to the site?

Lonneke, I think you may find quite a lot of use out of Layla Khashoggi's Car workout. I have personally found most of it very relevant for those long flights....
She even has a printout that you could pack in your carry on bag.

Thank you, Kristi!
