Tried it today with @dorag and we had a good time but WOW it’s hard
1) how to stay horizontal
2) once I rolled up semi vertically (with a big push from Dora I might add!) I struggled to do the mighty pull up to get all the wraps off. Dora was successful but she did about 3 hand over hand beast-mode climbs to get out of the wrap.
3) I too am looking for alternatives as I think this may be a several months-long training project to achieve
