For a commercial gym to cater to a wide audience, it's essential to have a mix of cardiovascular machines, strength training equipment, and a variety of free weights. It's also beneficial to include functional training gear like kettlebells, medicine balls, and resistance bands, which can add diversity to workouts and cater to current fitness trends.
The above said, many commercial ventures now follow more niche markets, such as small group training, personal training studios, class offerings, CrossFit gyms. These customised services necessitate a slightly streamlined requirement of gym equipment. This also implies reduced setup and operational expenses, aiming for a larger expenditure per customer.
