Fillipovich goes as far as to state that children younger than ten or eleven 2mg minipress amex, girls and boys, should not do any passive stretching at all; no contract-relax, no relaxed stretching, nothing of the sort! It also makes sense from the psychological point of view: youngsters just do not have the patience and body control necessary for sophisticated methods such as Forced Relaxation or tedious ones such as Waiting out the Tension (see Relax into Stretch). I must make a point that when one decides to place a heavy emphasis on active flexibility exercises for the legs, that is various slow leg raises and kicks, serious abdominal work must be undertaken first. In fact, until ten or eleven your gremlins should stay away from various forward and especially backward bends! On the other hand, the hip and ankle joints at this age are generally prepared for more serious stretching. Women who are pregnant or had a child within a few months should be especially careful with stretching and seek advice of their doctor. Delivery of a child requires extraordinary flexibility and the womans body releases the hormone relaxin to loosen the ligaments. They will not tear easily, but will stretch beyond the norm leading to joint instability. Adults should do it all: Relax into Stretch drills that teach their stiff muscles to yield to stretches, as well as Super Joints active stretches and mobility drills. Ditto for the older folks with more emphasis on mobility training than anything else. Youngsters must make active flexibility drills such as Reach the Mark and the Pink Panther their first, and sometimes only, priority. Kids should be especially careful in their stretching and other athletic pursuits when undergoing the growth spurt. Adolescent hormones try their best to keep the ligaments pliable to accommodate the mushrooming bones, but the best is not always good enough. Physical therapists have two definitions to describe a problem such as slouched shoulders: stretch weakness and tight weakness.
