User access to exercise with oxygen therapy (EWOT), therapy progress data, and user profile/record integration can be enabled via portable and wearable computing devices in use at treatment facilities is described. Embodiments leverage the field of wireless communications can access facility-based transponders, user authentication, data access, and data tracking. The invention enables access to oxygen therapy during exercise at various facilities by authorizing user access, tracking usage, providing access to user profiles/records, recording user progress, providing notification to providers of subsequent user treatment, and user record management based on proximity of a provider to a user during treatment. A safety harness system can include a circular padded rail to encircle the waist/torso of a user underneath the user's arms； hydraulically controlled legs can enable manipulation/movement under hydraulic control when the padded rail is secured to the user and while the user is moving on exercise equipment.
