A system for providing tactile input for prompting a person to coordinate appropriate muscle contractions during some form of physical movement such as exercising. The system may comprise a belt bearing inwardly facing projections adapted to make contact with a user's skin. The user may then be prompted by sensory tactile feedback or by audible, visible, or vibratory outputs to facilitate proper contractions, timing, and sequencing of activities, as may be appropriate given the type of physical activity. The projections are blunt, being hemispherical or hemispheroid, for example. The belt may include the projections, or alternatively, the projections may be attachable to a pre-existing belt. The projections may include transducers for providing signals to generate the audible, visible, or vibratory outputs. Outputs may be reproduced on a mobile communications device.
