Startup Idea: Customizable Fitness Tracking Software for Gym Owners

Startup idea to develop a customizable Software that would enable gym owners to provide tailored fitness and diet plans for their clients. The software should include features for tracking weightlifting programs, exercise routines and tie into meal and diet tracking efforts. It should be accessible on both desktops and through a mobile app.

I'm in the physical fitness industry - specifically, an owner of a CrossFit gym, or "box" as they're known.

My clients are often times needing customized fitness plans, and there seems to be a lack of software that isn't strictly phone based - and even then, apps are often configured for specific programs and are not easily modified to suit my customer's individual needs.

I'd like a piece of software that could track weightlifting programs, exercise plans, and also tie into their meal and diet tracking efforts - all accessible on their home computers as well as a mobile app.

Yes, I'd pay for software such as this, because it doesn't exist on the marketplace currently. It would solve a lot of problems, because I wouldn't have to have them create their own Excel spreadsheets or find workarounds for apps that may not fit their tailored exercise or diet plans.
