The BEST purchase for Nadia would be an elliptical trainer. Elliptical trainers provide a low-impact workout that is easier on the knees and joints compared to running on a treadmill. They simulate the motion of running or walking without the harsh impact associated with these activities, making them a suitable choice for someone with knee concerns while still allowing for effective cardiovascular exercise.
