I don't kneel, too hard to get back up. I bend over for as long as I can endure it. The knees have plagued me now and then since I was 20 something and showing Cockers. Couldn't get back up. My boyfriend(HA!) decided I was just lazy.
Yeah right. I loved shoveling pea gravel and it took three wheelbarrow loads to refill each run (7 of them). Loved shoveling snow. I think because of something Sour mentioned(when he cuts grass) . He could see the effects of his effort. Yep that's what motivates me. I have to see results.
I read something somewhere about bending at the waist being easier than kneeling for either spinal stenosis or degenerative disc disease. I'm the same way. I can bend over and touch the floor but cannot bend over and hold a 45 degree angle from the floor.
