Kettlebell coaches who run their own programs (private studios, garage gyms, online programming, traveling seminar coaches) usually have a built-in audience: their current clients, former clients, and the broader kettlebell community in their region. Branded coaching apparel turns that audience into a recurring side income line without the coach taking on inventory risk. Below is how the side hustle math works, what to put in the shop, and the realistic monthly numbers a kettlebell coach can expect at different audience sizes.

Affiliate program stack on top

A coach with regional kettlebell community connections can refer other coaches, other meet directors, and other gym owners into Pro Shops. The affiliate pays 10% of every referred subscription, forever, plus $1 per unit the referred shop sells. Five active referrals on the $59 VIP plan, each selling 30 units per month, pays the original coach roughly $180 monthly on top of her own shop revenue, with no extra work after the initial referral.

Done-For-You vs Self-Service for a busy coach

PlanCoach time per monthNotes
Self-Service VIP ($59)1 to 3 hoursCoach manages design uploads, product picks, retail pricing, occasional refresh
Done-For-You VIP ($109)5 minutes (send a logo)Coach sends one design per month, advisor builds the shop layout, picks products, sets pricing, configures previews

Coaches who run a full client load through training hours often pick Done-For-You because the time math works out. The $50 plan premium is worth more than the hour or two of monthly setup it would otherwise take.

Frequently Asked Questions

Does a kettlebell coach need an LLC or business setup to start the apparel shop?

No business structure required to open the shop. The coach signs up personally, the income flows to the registered account. Most coaches running the side hustle long-term do set up an LLC for tax simplicity once revenue grows past a few hundred per month.

How much upfront capital does the coach need?

Zero on the Free plan. $59 monthly on the Self-Service VIP plan. No inventory, no design fees, no setup fees.

How does the coach get paid for shop sales?

The margin between the VIP base price and the coach-set retail price is paid out bi-weekly to the coach account.

Can the coach run a private shop just for current clients?

Yes. The shop URL can be shared privately with the client list, posted on the coach website, or kept fully discreet outside the client base.
