A weight training facility is a place designated for strength-building exercises using any kind of weights or resistance equipment. These places may be used for improving or maintaining muscular endurance, strength, or size. Equipment may include free weights, weight machines, resistance machines, and other resistance-producing devices.

Resistance can come from free weights or from a machine or other device. The facility need not depend on one particular equipment type.

The intended work develops or maintains muscular condition. Rhythmic group aerobics is a different exercise format, while a fitness center can contain areas for both.
