This interior design sample shows the layout of free weights and exercise machines on the gym floor plan.
"Most health clubs have a main workout area, which primarily consists of free weights including dumbbells, barbells and exercise machines. This area often includes mirrors so that exercisers can monitor and maintain correct posture during their workout.
A gym which predominately or exclusively consists of free weights (dumbbells and barbells), as opposed to exercise machines, is sometimes referred to as a black-iron gym, after the traditional color of weight plates." [Health club. Wikipedia]
The floor plan example "Gym layout" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Gym and Spa Area Plans solution from the Building Plans area of ConceptDraw Solution Park.
