acceptability of deep knee bends & duck walk activities?

As a general exercise, they are really hard on the joints.  During basic training, I did my share.  I'm sure my knees would be in a lot better shape had I not been forced to do so many.

I don't know about most people but for me yes it would be since I already have arthritis in my knees and hands. \n  I think it a good way to get some exercise and not hurt yourself.\n  If you are young and in good health then go for it.

I agree with the afternoon walk idea - you could also try giving yourself a foot massage before bed to see if that helps.

squat all the way down with your derriere just above the floor and walk in a squated position as if you were pretending to be a duck and walk walk walk in that squatted position. You'll quickly start feeling your calves working hard. Also, if you lift your body in a controlled manner, with your metatarsals (on your tip toes) like in ballet, that works your calves as well. Your toes should be pointing outward not forward (think ballet positions -this would be first position). Hold our glutes, abs and the rest of your body up don't relax them and always keep your body controlled. Push yourself up from your calves and metatarsals. I hope I described these excersices enough to where you understand what I mean. Good luck!

If you have an 8 foot vertical jump (highly unlikely) then you needn't worry about improvement. It thats an error then you could try walking around on the balls of your feet all day and also calf lifts.

yes and no.  If there is constant tension on the quads, meaning you legs are slight bent, then yes.  If there isnt constant tension on the quads, then no.  You would get better results from doing elevated lunges with small weights.

Ask him to do some squats and work out a bit. That helps. Here's a site where he can help him do a little exercise...\n\nhttp://www.bodybuilding.com/fun/becker20.htm\nI would recommend the deep knee bends - they really work your a** off...

ok, assuming you're actually serious, it's an exercise\n\nlie down on the floor with your legs bent.  raise your chest to your knees with your hands interlocked behind your head.  you can also do them with your legs stright on the floor, or in other variations, but the first is most popular

I'm a white guy. DC resident all of my life. I know what you are referring to. We used to call it the "pimp-walk" (although my friends & I used to refer to it among ourselves as "breaking knee", just our own term.) I did it myself most of my life. Didn't really stop until around forty. (Still occasionally do it when alone!) It's simply a macho posturing thing & it serves it's purpose well! Always thought it looked cool myself but, of course, when one reaches a certain age, it does start to look a bit ridiculous. \nRemember the version of it that Sherman Hemsley did on The Jeffersons? Also, the late Leo Gorcey (Jewish/Irish) had his own variation in The Bowery Boys/East Side Kids movies!

i have one of those, they were great.  The key is to start out slow and hold yourself out as long as possible, make sure you have a pillow under your knees.  Try doing them in intervals of 25, maybe once in the morning and once before bed, then the next week do 35, and so on and so forth.
