Overview
The Gym is one of nine business types available in inZOI, introduced with the v0.5.0 update. Among all business options, the gym stands out as one of the most profitable choices thanks to its zero crafting costs and consistent revenue from entrance fees and paid lectures. A well-managed gym can earn between 18,000 and 23,000 Meow per day when the owner is present, making it a strong pick for players looking to build wealth without the complexity of recipe-based businesses like cafes or restaurants.
How to Start a Gym Business
Starting a gym follows the same general process as any other business in inZOI. You will need to purchase a commercial property, register your business through the Business App, and furnish the lot with the right equipment before opening your doors.

Purchase a commercial lot. Open the Edit City window and look for properties marked as Business Property. Commercial lots range in price from around 20,000 to over 100,000 Meow depending on size and location.
Register through the Business App. Use the Business App on your Zoi's phone to fill out the business registration form. Select the Gym preset, which automatically configures a management environment suited to fitness operations.
Place a kiosk. Every business needs at least one kiosk near the entrance as a point-of-sale terminal. Search for "kiosk" in Build Mode and place it where customers will naturally pass through. This is what allows visiting Zois to pay the entrance fee.
Add fitness equipment. Stock the gym floor with equipment from the Build Mode Furniture section (Hobby > Fitness). Treadmills, squat racks, punching bags, and yoga mats all give customers activities to do once they enter.
Place lecture boards. Lecture boards are the single most profitable piece of equipment in a gym. Place at least two so employees can teach paid classes to groups of customers.
Set an entrance fee. Unlike food-based businesses that charge per item, gyms charge an entrance fee that every customer pays on arrival. Configure this in Business Settings. The fee triggers regardless of whether a customer attends a class or just works out on equipment.
Equipment and Pricing
Gym equipment is purchased through Build Mode under Furniture > Hobby > Fitness. Prices range from just 5 Meow for a basic yoga mat up to 4,100 Meow for a treadmill. Here is a selection of available equipment:
Yoga Mat (5 to 23 Meow depending on variant): low-cost option for flexibility workouts
Hula Hoop (5 Meow): inexpensive cardio option
Dumbbells (24 Meow): basic strength training equipment
Barbell (64 Meow): another affordable strength option
Pull-up Bar (129 Meow): wall-mounted upper body equipment
Squat Rack (271 Meow): solid mid-range strength equipment
Punching Bag (337 Meow): builds both strength and cardio
Pulldown Machine (359 Meow): cable-based strength training
Barbell Bench Press (800 Meow): popular for chest and arm workouts
Treadmill (4,100 Meow): the most expensive piece, focused on endurance and cardio
You do not need to buy every piece of equipment to run a profitable gym. A practical starter setup might include a squat rack, a couple of yoga mats, a treadmill, and two lecture boards. This keeps initial costs low while still offering enough variety for customers. Equipment variety contributes to customer satisfaction, so adding more machines over time as your income grows is worthwhile.
Lecture Boards and Paid Classes
The lecture board is what separates a profitable gym from a mediocre one. When an employee uses a lecture board, they teach a paid class to a group of 5 to 6 Zois at once. Each Zoi pays roughly 560 Meow per session, meaning a single class can generate between 2,800 and 3,360 Meow in revenue.
For maximum income, place two lecture boards and assign employees exclusively to teaching duties. Classes marked with a "+Profit" indicator in the business interface generate direct income. There are also unpaid lecture options that may help train employees or improve customer satisfaction, though the exact benefits of free lectures are still being explored by the community.
The beauty of lecture-based income is that customers who enter the gym for a class often stick around afterward to use the exercise equipment. They have already paid the entrance fee, so every minute they spend on machines adds to the perceived value of the visit without costing you anything extra.
Revenue and Profitability
Gyms have a significant advantage over other business types: they have absolutely zero crafting costs. Businesses like bakeries, cafes, and restaurants require ingredients, recipes, and skilled cooks to produce items for sale. Gym revenue comes entirely from entrance fees and paid lectures, with no recurring material expenses.
With a well-managed 4-star gym that combines entrance fees, two lecture boards, and vending machines, players report daily earnings of 18,000 to 23,000 Meow after subtracting operating costs (employee wages, lot fees). On days when the owner does not visit the gym, income drops to roughly 6,000 Meow. This makes regular visits important for keeping revenue high.
Adding vending machines provides a small but passive income stream on top of the core lecture and entrance fee revenue. Vending machines do not require restocking or employee attention, so they are pure profit.
Employee Management
Hiring the right employees and managing them properly is essential to running a profitable gym. You can hire acquaintances or household members as staff. Employees must be Young Adults or older, and they will automatically clock in and out according to your set business hours.
Task assignment: For gyms, assign employees exclusively to teaching on lecture boards. This focuses their effort on the highest-revenue activity.
Wages: Salaries are calculated based on your business level, each employee's salary rank, and their working hours. Wages are paid out after business hours end each day.
Salary negotiations: Employees may negotiate salaries through conversations. Long working hours can also affect your relationship with them, so keep schedules reasonable.
Hiring capacity: The number of employees you can hire increases as your business level goes up. Starting out, you may only be able to hire one or two staff.
Existing jobs: If a hired employee already has a job elsewhere, they will automatically resign from it before joining your business.
Customer Satisfaction and Star Rating
Customer satisfaction determines your gym's star rating, which in turn affects foot traffic and revenue. Several factors influence how satisfied visitors feel:
Quality and variety of fitness equipment
Furniture quality and overall lot decoration
Pricing (entrance fees that feel fair for what is offered)
Employee responsiveness and service quality
Frequency of available business activities like classes
Your personal relationship with customers as the owner
Higher star ratings bring more customers through the door. A 4-star gym significantly outperforms a lower-rated one. Investing in better equipment, decorating the lot with appealing furniture, and keeping employees focused on their tasks all contribute to climbing the star rankings.
Owner Presence Matters
One important detail that sets gyms (and all businesses in inZOI) apart from fully passive income sources: your presence as the owner makes a real difference. When you visit your gym and actively manage operations, the business attracts more Zois and generates its peak earnings. If you skip visiting for a couple of days, customer flow drops and your reputation can stagnate.
The difference is stark. Active management yields 18,000 to 23,000 Meow daily, while neglecting the gym drops income to around 6,000 Meow. If you own multiple businesses, try to rotate visits so each one gets regular attention.
Tips for Running a Profitable Gym
Start with a gym as your first business. The zero crafting costs and straightforward setup make it beginner-friendly compared to food-based businesses.
Place at least two lecture boards and set employees to teach paid classes. This is where the bulk of your income comes from.
Add a couple of vending machines for passive bonus income that requires no employee effort or restocking.
Visit your gym regularly. Owner presence significantly boosts customer flow and daily earnings.
Keep entrance fees reasonable. Setting fees too high can drive customers away and lower satisfaction.
Upgrade equipment and decorations gradually to raise your star rating, which increases foot traffic.
Assign employees exclusively to teaching rather than splitting their focus across tasks.
