Ascending - Frog Type Systems

This videos illustrates one of the ascending techniques used in the Cornell Tree Climbing Institute's instructional classes. This information is not intended to be an online tutorial for beginners. Our intent is to share these general procedures with other qualified professionals who are interested in developing a college-based recreational tree climbing program. Tree climbing can be hazardous! If you are new to tree climbing, seek qualified instruction before attempting these techniques.

I see how the micro pulley makes your day easier in the yo-yo setup. Is it necessary, though?  Looping the rope through the carabiner after exiting the grigri should work almost as well, right?

[CornellTreeClimbing]

@Badgerheist Your suspicion is correct - the micropulley isn't necessary. You can just redirect through a carabiner, but as you get higher the weight of the hanging rope gets pretty onerous. For that matter you can simply step up in the upper ascender and yank in the slack with no redirect at all, but that motion is ergonomically challenging. Hanging the pulley off the top hole of the ascender can make this a little more efficient, but no matter what, this way isn't idea for long climbs.

Your voice is fine for what you're doing, and your vids are good.

Where this one needs improvement is in technique. You're working harder than necessary because you're not keeping your feet under you and standing straight up. The girl's technique is worse. She's pushing almost straight down with her foot, but from an extremely inefficient position. Her foot loop should be longer, so the stroke starts with a minimal bend in the leg and ends at full extension.

@NYpaddler Good observation. Tho, practices vary according to personal preference. My friend Dave uses a standard length runner for a foot loop and has a huge throw. It's less efficient, but faster and he has power to spare.  I agree that Sarah's foot loop is short, but we weren't paying too much attention to efficiency, just getting the general idea of the connectivity of things. I'd say the maximum efficiency with the yo-yo uses no step up at all, only laying back and raising the hips.

Yeah, lucky it's not my voice commentating, it would really suck to have a nice voice doing it. I'm just saying it really is an unbearable voice, gotta be someone else to do it, how about one of the girls in the vids??

@BCo181INF The next video we post will certainly be narrated by someone else. I think we've heard this same feedback enough times.

Great videos, thanks! And your voice is fine..

Great vids! I enjoyed the multitude of techniques explored. And heh, I find the voice calm and concise, ideal for an instructional video.

@CornellTreeClimbing Your voice is fine, dude. Some people are just twits. I really appreciate all these videos you've put up. Thanks!
