A two-year-old gym operator out of Birmingham is close to signing franchise agreements with two Nashville-area entrepreneurs. The Birmingham News says the two locations will go north and south of the city's core.

Iron Tribe began with a single gym in a garage in Homewood in 2010 and today has four Birmingham-area locations. The gyms specialize in a system of training that combines a variety of types of exercise in short, intense sessions. Membership in Iron Tribe facilities is capped at 250 people per gym, and fees average about $250 per month.
