A portable wall-adhering exercise aid is provided. In an implementation, the exercise aid includes a sheeted material that removably adheres to a wall or other surface and provides a low-friction surface for exercise support. The exercise aid can provide balance to a user during exercises, such as back exercises, and can bear some of the weight during exercise making the exercise session more attractive. The exercise aid may include pressure sensors and heart sensors. An embedded processor may provide real time feedback and provide programmed exercise routines. The processor and a transceiver may also enable remote control or establish telemetry for remote monitoring.
