An exercise system may include an exercise device, which may be configured to facilitate personal exercise and quantification thereof. The exercise device may include a housing body configured to receive compressive force during personal exercise. Personal exercise may include an exercise performed by a user involving one or more body parts of the user. The exercise device may include a force sensor carried by the housing body. The forces sensor may be configured to generate an output signal responsive to compressive force being exerted on the housing body. The exercise device may include one or more processors carried by the housing body. The one or more processors may be configured to execute one or more computer program modules to, among other things determine one or more exercise parameters based on the output signal of the force sensor.
