I tried to find the knee walking video because I just couldn't believe it! I'm wondering if the technique is associated with Japanese or Chinese practice? I couldn't find one with a PT demonstrating, but I saw several that were illustrating moves form Aikido or some such. I saw one example where only
@Fire wolf could possibly do it--you'd need a really good bend like she has just to get started!

None of us slow-benders would qualify. Well, maybe
@kmak81230 would attempt it, because she just hiked an amazing amount of miles this past weekend!

The knee-walking technique I saw would definitely take a lot of "mind over matter". AND more grit than I possess just to try.
My PT has me do an-on-the-knees exercise that utilizes gravity (her favorite thing) to increase bend. It's a killer but not in the bad sense. You get on all fours and then move your bottom back toward your heels and hold it for 3 minutes. If it gets too uncomfortable, you move back into the straight-up position for a few seconds and then resume. This exercise is how I learned to trust that my knees will hold up to kneeling. I started on the PT bench with a pillow under the knees, then tried it on the bench surface without the pillow--I like that much better. At home, I was doing it on my bed, but that was too soft. I kept feeling like I was going to fall over on my side! I found out that I could handle doing the exercise on carpet quite easily. And I can kneel for other purposes on carpet, bed, leather-like upholstery, etc. Just not on hardwood, cement, or asphalt. This is quite exciting, as kneeling has been almost impossible for me for several years.
Good for you,
@Pheebs52, at being able to lift that giant, jiggly, jello bowl! I think the secret to doing some of these dicey things is to go slowly and think through each move.

I've been doing squats with the TRX machine at PT, and recently I could do them while keeping the pull-straps slack. My cat isn't a 28-lb bowl of jello, but she does weigh about half that plus a couple of pounds,
and she goes limp when I pick her up, just like a toddler often does. I've re-injured my back before, picking her up. So she is a risk that I haven't been taking. But when I realized that I was stable enough to do a full squat without strap aid, I did start picking her up again the other day. Twins!
