Personal Trainers Running a Birthday Shirt Side Business

Personal trainers with an established client base and community presence have a natural audience for a birthday shirt side business. A PT who opens a Bear Grips shop, designs a birthday shirt program, and promotes it to their gym community has a recurring product that sells around member birthdays year-round.

The economics: at $12 to $16 profit per cotton tee, a PT with 50 active clients and 12 birthdays per month in their community generates $144 to $192/month from birthday shirt sales without adding training hours.

Frequently Asked Questions

What is a good birthday shirt design for a personal trainer?

A years-in-the-industry badge with the PT's name and birth year is the most meaningful for experienced trainers. A certification reference or client milestone design works for trainers who identify strongly with those achievements.

Can clients chip in together for a personal trainer birthday shirt?

Yes. No minimum means any client group size works. One client creates the shop, uploads the design, and shares the link. Free shipping to any US address.

Can a personal trainer use Bear Grips Pro Shops to sell birthday shirts to clients?

Yes. Open a free shop, set up a birthday shirt design, and share the link with your gym community. Earn the margin on every sale with no inventory or shipping management.

How long does a personal trainer birthday shirt take?

5 to 7 business days for production plus free shipping transit. Order at least 10 to 14 days before the birthday.
