Popularizacija online oblika suradnje s osobnim trenerima dovela je do potrebe za adekvatnom programskom potporom za taj način rada osobnih trenera s njihovim klijentima. U sklopu ovog rada implementiran je sustav koji olakšava takvu suradnju omogućavanjem komunikacije između osobnih trenera i njihovih klijenata te pregled podataka vezanih uz suradnje s osobnih trenera, poput praćenja izvedenih vježbi i tjelesne mase klijenta.
