Using a mini-band during push jerks to help Karen keep her knees out. When approaching 85%+ weights Karen suffers from excess valgus during the jerk drive. This is not an issue in any squatting pattern and only happens during the rebounding forces associated with the jerk. There are numerous causes for valgus (weak hips, poor ankle mobility, bad motor patterning) and it can also be a more common occurence for female lifters (due to larger Q-angles relative to males) but the key is to determine what specific area the lifter is lacking and address it. In this case, as there isn't a problem with any other squatting or even jumping pattern, the idea is to strengthen the hip and glute muscles to stabilise the eccentric and rebounding forces of the jerk while simultaneously re-learning the actual motor pattern of the movement, for which the mini-band seems to be working wonders. #teamcsp #motorpattern #valgus #jerk #weightlifting #gym #bray #wicklow #brayandwicklowspremiergym #irelandspremiergym .
