how are people double jointed and why?

The term "double jointed" means having joints loose enough to snap in and out of regular position.  There is no difference in their bones, but in the tendons that connect, support and move those bones.

It's about balance. Try to imagine your weight centered exactly between your two hands. Try to arc your palms, too.

My dad has one leg shorter than the other and they built up the shoe on the shorter leg so they would both be even. He has a lot of hip and knee trouble and the doctor said that is what was causing it. So he had his shoe built up and he said it's somewhat better now.

You could use 2 legs, use a large wedge or just use a ramp type object.

It is for balance. You can yourself do this experiment. Sit down like a cow and try to getup in usual way, you may find it to get up, now try in the cow's way, no you can get up easily. \n\nIn the same way sit with crossed legs and get up to stand, you can't, now try to get up with hands stretched or hands in the floor acting as support, now you can get up easily. \n\nIt is in same principle like a rope-walker using a long pole to walk across a tight rope.

because they're are 2 openings for each of u're legs, which comes in 2... remember: pair - something that comes in 2's.......

From joints or bone?\nSee a physician.  This is not a do it yourself project.

The definition of the joint is the meeting point of two extemities.Down from the neck,the shoulders and the arms,the elbow,the wrists,the fists,the back,the legs,the knees,the ankles,the foot plant.

Can be active or passive.  But they are simply exercises to increase the motion at a joint.

A joint (articulation) is the location at which two bones make contact (articulate). Joints are constructed to both allow movement and provide mechanical support.\n\nStructurally, joints are classified as:\n\nfibrous - bones are connected by collagen. \ncartilaginous - bones are connected by cartilage. \nsynovial - there is a space (synovial cavity) between the articulating bones. \n\nFibrous joints\nIn fibrous joints bones are joined by tight and inflexible layers of dense connective tissue, consisting mainly of collagen fibers. In adults, these are not designed to allow any movement; however, in children, fibrous joints have not solidified and are movable. Examples of fibrous joints are:\n\nCranial sutures, joining the bones of the cranium. \nGomphoses, the joints between the roots of the teeth and their sockets (or alveoli)and in maxilla and mandible.g \n\nCartilaginous joints\nIn cartilaginous joints (also known as synchondroses) bones are connected entirely by cartilage. In comparison to synovial joints, cartilaginous joints allow only slight movement. Examples of cartilaginous joints are the pubic symphysis, the joints between the ribs and the sternum, and the cartilage connecting the growth regions of immature long bones. Another example is in the spinal column - the cartilaginous region between adjacent vertebrae. and are made of cartilage.\n\n\nSynovial joints\nSee synovial joint for details. (The term "Synovial joint" and "Diarthrosis joint" are often used interchangeably, although the first term refers to the structure and the second one to the function.)\n\nFunctional classification\n\nFunctionally, they can be classified as:\n\nsynarthrosis - permit no movement. \namphiarthrosis - permit little movement. \ndiarthrosis - permit a variety of movements (e.g. flexion, adduction, pronation). Only synovial joints are diarthrodial. \n\nSynarthrosis joints\nSynarthroses are joints with very little (if any) mobility. They can be categorised by how the two bones are joined together:\n\nSyndesmoses are joints where the two bones are joined by one or more ligaments. \nSynchondroses are joints where the two bones are joined by a piece of cartilage. \nSynostoses are the fusion of two bones, to the point that they are practically one bone. In humans, the plates of the cranium, initially separate, fuse together as the child approaches adulthood. Children whose craniums fuse too early may suffer deformities and brain damage, as the skull does not expand properly to accommodate the growing brain - a condition known as craniostenosis. \nAmphiarthroses are slightly moveable joints where the two bone surfaces at the joint - both covered in hyaline cartilage - are joined by strands of fibrocartilage. \n\nAmphiarthrosis joints\nMost amphiarthrosis joints are cartilaginou

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.

because in everyday life, you do not use muscles in isolation, it is more beneficial to use multiple muscles at once when weight training also, for equal strength buildin, so one is not compensatin for the other, they are working in unison - hope that makes sense! :-)

It's "diarthrotic" joints.  They are freely movable joints such as the elbow and knee.

I've always been a fan of a low single brought up tight under your arm to keep your opponent off balance and then even tree-top him (push his leg to the sky) if you can.  Arm drags and lateral drops are tough to get away with at higher levels of wrestling.  As for a double leg, using your shoulder may be effective, but its best if you shoot in wrap your arms around their calves to prevent a sprawl and then drive at a 90 degree angle (rather than straight into him) using your head and leg.  I also like a defensive takedown by letting an opponent shoot in on a single, throw in a whizzer, then either break his grip and shoot while your in close or hit a cutback/gramps as you turn into him.

Because we have muscles on both sides of our fingers - or rather, tendons.  Our legs and our arms are the same way.  In order to extend our fingers or to clench our fingers, we have to use opposite muscles in order to do so.  When we relax BOTH sets of muscles, we end up in the middle, and hence, our fingers take on a curved look.

Your joints are wearing out.  Before long they will get harder too move with limited range, then it gets worse.

compound ones.....use more than one joint\nClean and Press...Snatch...Squats....Deadlift..Chin/Pull Up...Bent over Row...Military Press...Bench Press...In that order
