How to Grow a Basketball Training Business: From $40K Side Hustle to $149K
How a Grocery Stock Clerk Built a $149K Basketball Training Business
Marco came to the US from Serbia barely speaking English.
He spent two years in a grocery dairy department. Stocking shelves. Stocking eggs. Training kids on the side at a rec center for $40 an hour whenever he could get the time.
In 2024, his basketball training business did $149K in revenue. By July 2025 he was at $112K — on pace to clear $200K for the year.
He didn't get lucky. He didn't go viral. Two things changed, and they're the same two things keeping most trainers stuck under $50K.
The money problem was in his head, not his market
Marco had to stop believing money was evil before he could charge what his training was worth.
That sounds soft. It's not. It's the single most common ceiling I see across the 2,500+ coaches I've worked with since 2016. The trainer who won't charge $3,000 for a program isn't held back by his market — parents in every zip code pay that for travel ball, private lessons, and club fees. He's held back by what he believes about himself and about money.
Marco's wake-up call came while stocking eggs in that dairy department. He looked at where he was, looked at where he wanted to be, and decided the story he'd been telling himself about money wasn't serving him.
Once that shifted, everything downstream got easier. Raising prices. Asking for commitments. Saying no to the wrong clients. The mechanics of growing a training business are simple — the belief has to come first.
He stopped selling sessions and started getting commitments
This is the mechanical shift. Marco stopped selling individual sessions and started getting parents committed to programs.
One parent on a 12-month program is worth ten parents buying sessions one at a time. Not just in revenue — in retention, in results, in referrals, in your sanity.
Do the math on sessions. At $60 a session, a $5,000 month means 84 sessions. That's 20+ sessions a week, every week, with no cancellations, no holidays, no slow season. Now factor in reality: players cancel, families go on vacation, the off-season dries up. The session model has a ceiling, and most trainers hit it somewhere between $3,000 and $5,000 a month.
Marco's model looks nothing like that. Committed parents on real programs. Recurring revenue. A calendar that doesn't collapse every time club season starts.
Full-time was a decision, not a milestone
In 2022, Marco was doing $40–50K and still wasn't full-time. He was waiting until the business felt “ready” to make the leap.
It doesn't work that way. The revenue followed the commitment, not the other way around.
The trainers who go full-time don't wait until they feel safe. They commit, burn the backup plan, and the business grows into the space they cleared for it. Marco went from the dairy department to full-time doing what he loves — and the naysayers who told him it wouldn't work got to watch it happen.
That's not recklessness. That's understanding that a part-time business gets part-time results. You can't build a $149K business on nights and weekends while your real energy goes to stocking shelves.
The naysayers were wrong (and they always are)
People told Marco it wouldn't work. They always do.
When you're stocking shelves and telling people you're going to build a six-figure basketball training business, the room goes quiet. Friends worry. Family suggests you be realistic. Other trainers tell you the market is saturated.
Two years in a dairy department, then full-time doing what he loves. The proof is the business.
Here's what I've learned across 2,500+ coaches: the naysayers are almost never people who've built something themselves. They're people projecting their own ceiling onto you. The trainers who actually make it — Marco, Hector ($18K to $200K), Coach Marcus ($500K/year part-time) — all heard the same thing. They all did it anyway.
If everyone around you thinks your goal is realistic, your goal is too small.
Frequently asked questions
How long did it take Marco to go from side hustle to $149K?
A few years of committed building. In 2022 he was at $40-50K and still not full-time. By 2024 he hit $149K. The timeline compresses once you fix the offer — most trainers stay stuck for years because they're selling sessions, not because the market is slow.
Do I need to quit my job to grow my training business?
Not on day one. But at some point the part-time ceiling becomes real. Marco's revenue followed his commitment, not the other way around. Build the offer first, get real clients on real programs, then make the leap when the math supports it.
What if I don't have Marco's story?
You don't need an immigrant-underdog story. You need the two shifts: fix what you believe about money, and stop selling sessions. Those work regardless of your background.
What this means for you
If you're still trading hours for dollars, Marco's story is the roadmap:
- Fix the money story first. If you flinch at charging real prices, no marketing tactic will save you. The ceiling is internal before it's external.
- Sell programs, not sessions. A defined program with a real price and a real commitment. Everything — revenue, retention, referrals — follows from this.
- Commit before you feel ready. Full-time isn't a milestone you reach. It's a decision that creates the milestone.
Marco went from no English to living off basketball in a few years. Not because he's special — because he did the two things most trainers won't.
