Joint Mobility...a few suggestions

Per the Z-Health Sport Phase manual:
"As Alwyn Cosgrove says, the amount of time invested in any given training session to mobility work, should be related to how poorly the athlete moves. Very tight, motor-challenged athletes need to spend up to 20 minutes on this phase of training. Highly athletic, well-trained clients may only need 5-8 minutes to get ready."

Additionally, sports specificity and/or the specific injury position may be overlooked in joint mobility application. Therefore it may be necessary to simply perform your joint mobility while lying, seated, or standing. Try to move all your joints through their full pain-free ranges in the three varying positions. You may find it provides different mobility and new "releases." You may be surprised too, at how well the joints move in the very practiced standing position, but are more difficult to control or even figure out in the seated and lying positions.

However, the most practiced position of your typical athlete (the desk jockey) is seated; and so practicing high quality seated mobility is very applicable to their specific daily needs and movements.
