A local fitness operator with 11 clubs in Chicago, US, is looking to muscle in on the increasingly crowded on-demand, at-home fitness market by launching its own offer.

Fitness Formula Clubs (FFC) was founded in 1984 and has eight clubs within the Chicago city limits and three in the near Chicagoland suburbs.

It has now set up the FFC On Demand mobile and website app in partnership with its technology partner Virtual Health Partners.

Priced at US$14.95 a month, the service features group fitness content featuring a wide range of classes – from HIIT and strength classes to dance and yoga – recorded at FFC studios.

It also offers nutritional advice, including recipes and unlimited messages with nutrition specialists; lifestyle content on behavior modification, mindfulness and overall wellness; and monitoring tools on food intake, diet adherence and weight loss.

The service also integrates with Myzone and other popular fitness trackers.

According to Gale Landers, FFC founder and CEO, the platform looks to add a local alternative to the existing array of on demand services.

"Our commitment is to meet the health, fitness and wellness needs of Chicago and the surrounding communities while delivering a consistent overwhelming value proposition at an ultra-convenient location," Landers said.

"With this launch, ultra-convenience has been redefined. We are thrilled to be able to extend our service offerings with FFC On Demand."
