iTrain is a mobile fitness app that provides customized workout programs, music, and training guidance to mainly young adults aged 15-40 who enjoy linking technology to their exercise routines. It offers a complex free virtual environment that allows users to work on their own schedule and body parts of choice, saving both money and time compared to traditional gyms. The app generates revenue from paid training programs, music, DVDs, gift certificates, and affiliate marketing commissions. There are opportunities to expand revenue through international localization, advertising partnerships, an online store, optimizing the mobile website, and broadening the target user base to include seniors through online coaching.
