Traditional gyms often need cardio machines like treadmills and strength training equipment like free weights, while specialized studios such as yoga or Pilates spaces may require mats and balance balls. Functional training gyms could focus on kettlebells and TRX systems.

Commercial-grade fitness equipment is designed and tested for use in health clubs, gyms, resorts, and athletic team facilities where equipment is used for 12 or more hours per day.

A rule of thumb for the cost of gym equipment is $25 per square foot. So, for a 3000 square foot gym, your equipment is going to set you back around $75000. If you decide to buy your equipment by way of an equipment loan, you will have an ongoing expense of $1000-$2000 per month (and you'll be paying interest on it).
