How many exercise machines do you need for your gym: calculation based on area, standards, and occupancy

When planning to open a gym or upgrade an existing one, the first question is always the same: how many machines do you need? Errors on the underside mean customers will have to wait in line during peak hours. Errors on the overside mean freezing your budget on equipment that sits idle for half a day. In this article, we'll examine the calculation methodology based on three key parameters: standards, occupancy, and area. For commercial facilities, choosing the right amount is crucial. gym equipment, designed for intensive use, this affects both the calculation and the long-term maintenance budget.

Basic standard: where does the figure “6 m²” come from?

The starting point for any calculation is the regulatory framework. According to SP 31-112-2004 (Code of Practice for Physical Education and Sports Halls), at least 4,5–6 m² of usable areaImportant: This refers to usable space, excluding changing rooms, showers, reception, and technical areas.

GOST R 57116-2016 "Fitness Services. General Requirements for Fitness Facilities" adds a capacity standard: at least 5 m² per visitor, located in the hall at the same time.

Practical example: the hall is 200 m², of which the usable area is 160 m².

• According to the equipment standard: 160 ÷ 6 = 26–27 units

• According to the capacity standard: 160 ÷ 5 = 32 people at a time

This is a starting point, but not the final answer—the actual figure is adjusted by three additional factors.

Three factors that change the calculation

1. Object type

The fitness club, the hotel gym, and the residential complex gym represent three distinct usage scenarios. Hotel guests exercise for 20–30 minutes in the morning, with a consistent intensity throughout the day. Residents of the residential complex primarily come in the evening. Fitness club members are the most diverse group, with distinct peaks in activity.

For a small hotel (50-80 sq m for a gym), 8-12 units are sufficient: 3-4 cardio machines, 4-6 strength stations, and a basic set of free weights. For a mid-sized residential complex (80-120 sq m), 12-18 units with an emphasis on multifunctionality are sufficient. For a commercial club, the relationship with area is nonlinear: the larger the gym, the more important zoning is.

2. Peak load

This is the most critical parameter, which is often ignored. In most Russian gyms, peak time is 18:00–21:00 on weekdays: 40-60% of all daytime traffic occurs during these hours.

Calculate how many people will be in the hall at one time during peak hours. To do this, you need turnover ratio — the average workout time per user. For a gym, this is 50–70 minutes. If 40 people are signed up during peak hours, and the average workout is 60 minutes, then the gym will currently have 35–40 people. Each person is allocated 5 square meters of space according to the standard. This is the actual estimated capacity.

3. Ratio of zones

The optimal equipment structure for most commercial halls:

• Cardiozone — 40–45%: treadmills, ellipticals, exercise bikes, steppers

• Power zone — 35–40%: block trainers, lever machines, benches

• Free weights and functional training zone - 20–25%

The more "massive" the club, the higher the proportion of cardio: beginners and weight-loss seekers make up the majority of the clientele. A gym for experienced athletes shifts the balance toward strength training.

Distances between exercise machines: what the standards say

Maintaining proper clearances is both a regulatory and practical requirement. Clients shouldn't feel squeezed between two treadmills.

Minimum distances:

• Between cardio machines - at least 90 cm on the sides, 150 cm at the back

• Between strength training machines - not less than 100 cm

• Free weights area - not less than 200 cm between the racks and benches

• Aisles between rows - not less than 120 cm (fire safety requirement)

It is because of these gaps that the “theoretical” calculation of 160 ÷ 6 = 26 exercise machines in practice often yields 20–22 units: part of the area is spent on mandatory indents.

Step-by-step calculation algorithm

Step 1: Determine the usable area: total area minus auxiliary areas. Typically, this is 60–70% of the total area of ​​the property.

Step 2: Calculate the maximum one-time capacity: usable area ÷ 5 m².

Step 3: Determine peak traffic. For a new hall - the planned number of season tickets x 0,10 (on average, 10% of the base are in the hall at the same time during peak times).

Step 4: Take the larger of the two values — capacity by area and peak attendance. This is the estimated number of seats.

Step 5: Distribute equipment into zones in the proportion 45/35/20 (cardio/strength/free weights) adjusted to the profile of your audience.

Calculation example. The hall is 300 m², the usable area is 190 m², the planned base is 350 season tickets.

• Capacity by area: 190 ÷ 5 = 38 people

• Peak load: 350 × 0,10 = 35 people

• Estimated number of seats: 38

• Equipment: ~17 cardio machines + 13 strength machines + 7-8 free weights = 37–38 units

Typical mistakes when purchasing

Buy for growth without taking into account peaks. If equipment operates under constant overload, its service life is exhausted 1,5–2 times faster than the scheduled service life. Commercial exercise equipment is designed for a certain number of hours of operation per day—this limit should not be systematically exceeded.

Ignore the service area. Each piece of equipment must be easily accessible for maintenance. This directly impacts the layout and final number of positions.

Equal emphasis on all areas. In most gyms, treadmills are used two to three times more intensively than, for example, a back row. Analyze your audience profile before making the final purchase—this will save you money and space.

Do not set aside reserves. 10–15% of equipment may be undergoing maintenance or repair at any given time. This reserve should be factored into the calculation from the outset, rather than added later.

Сonclusion

Correctly calculating the number of exercise machines involves working with three numbers: usable area, peak occupancy and audience profile. SP 31-112-2004 and GOST R 57116-2016 standards provide a lower limit, but actual use will adjust it. The formula "area ÷ 6 m²" is a good starting point, but the final figure is always slightly lower due to mandatory clearances and zoning.

Once the calculation is ready, the most important thing is to select the right models for each zone: reliable, with a warranty, and designed for intensive commercial use, not domestic use.
