This case involves a 55-year-old woman who tore a ligament in her hip while performing deadlifts with her personal trainer. The woman weighed 148lbs during the time of the injury and had been working with this trainer weekly for one year. At the time of the injury, the trainer had the plaintiff lifting 135lbs, for 3-4 sets of 15 repetitions. Following the injury, the plaintiff was never able to recover full mobility in her right leg. An expert in personal training and exercise science familiar with the written literature regarding the proper execution of deadlifts was sought opine on whether or not the trainer had his client working at her appropriate base level during the time of the injury.
