The plaintiff was injured in an exercise class while using a bouncing air-filled ball for a slam ball exercise. Following a trial, Justice Brown held that the defendant fitness club met the applicable standard of care. First, the slam ball exercise was not inherently dangerous or complicated. The use of an air-filled ball for the exercise fell within industry standard. Further, the instructor properly prepared the room for the exercise and gave appropriate instructions (including a demonstration) with respect to the exercise. The plaintiff had also done the exercise and received instruction on the exercise in the past. Finally, it was not negligent for the instructor to turn her back to the class briefly in order to start the timer for the exercise.
