Method and system for virtual fitness training and tracking service

A system comprising:

• an Exercise Management System (EMS) comprising:
• one or more weight sensors, wherein at least one of the one or more weight sensors comprise a strain gauge;
• one or more relief features, wherein the one or more relief features concentrate a weight in at least one predefined and fixed area relative to the one or more weight sensors;
• one or more motion sensors;
• and
• a processor having memory, the processor configured to:
• determine a weight lifted based on a measured strain on the one or more weight sensors;
• determine a movement of the weight lifted based on a measured motion of the one or more motion sensors;
• and
• determine, based on the determined weight and the determined movement of the weight, at least one of:
• a number of sets, a number of repetitions, a lifting speed, a range of motion of the weight, an energy, a maximum power, and a total calories spent;
• wherein the one or more sensors further comprise:
• a weight sensor of the one or more sensors disposed in a weight pin of the exercise equipment, wherein the weight sensor measures a weight lifted, wherein the weight pin further comprises one or more pin relief features, wherein the one or more pin relief features concentrates the weight and support forces on one or more predefined and fixed areas of the weight pin, and wherein the one or more pin relief features comprise two pin relief features disposed about each of the one or more weight sensors;
• and
• a rotation sensor of the one or more sensors disposed about the weight pin, wherein the rotation sensor measures the movement of a cable of the exercise equipment about a rotatable pulley.
