I’m not sure if you can do an Anti-G Straining Manoeuvre (AGSM) while reverse bangee jumping…

…whatever that is! :confused:

To do the G maneuver while inverted would be dangerous and would be the opposite of what you need to do physiologically.

It sounds more like he is getting motion sickness.

All I usually get from inverted G is a headache and tired. Yes you can get nauseous, but most people get over it right away.

I think some people get nauseous because the extra blood to the inner ear and brain can throw your senses off. However most people recover quickly after returning to positive G..

I agree with kicks some moderate weight lifting/strengthening exercise should help some.

If you’re just having motion sickness, just a little practice on the bungee cord will probably build your tolerance up.
