A custom t-shirt side hustle for a fitness business earns $8-15 per shirt with no inventory, no upfront printing cost, and no box of unsold shirts to move. The shirt is printed after someone orders it. Your role is to set up the shop, upload your design, set your price, and share the link. This guide covers realistic income from a fitness shirt side hustle, the best shirt styles to offer, and pricing that converts your existing community into buyers.
The traditional shirt business problem is inventory risk: you order 50 shirts, some sizes do not sell, and you have cash tied up in boxes. Print on demand eliminates this entirely:
No minimum order. No prepayment. No size guessing. No storage. The only investment is the time to set up the shop, which takes under an hour for a fitness business with an existing logo file.
Income from a fitness business custom shirt side hustle is directly tied to existing community size and engagement:
| Business Type | Members/Clients | Annual Shirt Income |
|---|---|---|
| Personal trainer (20 active clients) | 20 | $100-200 |
| Small gym (60 members) | 60 | $300-500 |
| Mid-size gym (120 members) | 120 | $700-1,000 |
| CrossFit box (200 members) | 200 | $1,200-1,800 |
| Run club (100 members) | 100 | $450-750 |
| Yoga studio (80 students) | 80 | $350-600 |
These estimates use a 60-65% buy rate and $8-10 margin per shirt. Adding a second shirt design, seasonal drops, or event shirts pushes income higher. The sweatshirt and hat additions typically increase annual income by 40-60% over shirts-only shops.

Pricing too high reduces buy rate. Pricing too low reduces margin. The sweet spot for fitness community shirts:
Run a simple mental test: would your average gym member pay this price for this shirt at your front desk? If the answer is hesitant, lower the price. If the answer is immediate yes, you may have room to go slightly higher. See the custom shirt income guide for detailed margin optimization.
No inventory, no upfront cost. Upload your logo, set your price, earn on every shirt your community orders.
Start FreeFor a fitness business with 80-150 engaged members, expect $40-150/month in ongoing shirt income after the initial launch spike. The first month typically earns more because of pent-up demand. Ongoing monthly income depends on new member additions, seasonal drops, and how actively the shop is promoted.
No. With Bear Grips Pro Shops, shirts are printed after orders come in. You pay nothing until a sale is made. The buyer pays the retail price, the base production cost is deducted, and your margin is the remainder. No upfront purchase required.
Yes. Your shop can carry multiple designs simultaneously. A seasonal design alongside your core logo, a limited-edition event shirt, or a design for each program you run. Each design is uploaded separately and applied to products independently.
