She is full of it. I climb for a living and for recreation-trees, rocks, glaciers, windmills, radio towers, etc. and even teach rope rescue courses for several of the local fire departments. There is not a saddle on the market that would go around her waist, they top out at around 45 inches and if you are climbing in winter weather, you lose a couple inches just from the heavier clothing. Not to mention the fact that she is so top heavy, I've got to wonder how she stays upright on rope.
If you weren't one of the bullies who doubt her incredible resume and asked that, she'd probably tell you how she learned to tie a Swiss seat while she was telling the rappelling instructors what they were doing wrong at Air Assault School. Of course she'd spell it wrong, so it'd probably come out like 'Switz set,' or something.
