Isometric exercise devices

Abstract

Isometric exercise devices including a force input member, an elongate tension bearing member, and a body interface member. The force input member is configured to be pushed or pulled by a user. The elongate tension bearing member develops tension when the user pushes or pulls the force input member and the body interface member is restricted from moving by abutting the user. The elongate tension bearing member operatively couples to the force input member. The body interface member is configured to abut the user. The body interface member operatively couples to the elongate tension hearing member. In some examples, the isometric exercise devices include a frame and/or a strain gauge. The strain gauge may couple to the elongate tension hearing member and be configured to detect tension developed in the elongate tension bearing member.
