Big wall rock climbers and vertical cavers need to deal with the same,
and some of their gear and techniques may be helpful.

For example, when suspended on a rope, in harness, you could use a
loop of cord with a Prusik hitch, attach it to the main rope, and give
yourself a loop to stand on and get some more leg circulation.

There are other techniques used by belayers, as they may be in place
for extended times, and not able to let go of the rope their partner
is on.

As always, this is dangerous stuff, and should only be done with
proper instruction and equipment. Gravity is not always your friend.

Happy trails,
