How do you add $200,000 to your gross revenue?
Start by adding $260 a week.
That’s what Erik Zeyher did at Warlock Athletics in New York.
He added one semi-private training session a week, sold it out in 45 minutes with a Facebook post and then slowly grew the program into a revenue stream that contributes $200,000 to his total annual take.
You can do the same thing.

Thinking about adding six figures to your gross can be intimidating—especially if your gym is only grossing $150,000 or $200,000 right now.
But it can be done.
About two years ago, Erik wanted to solve problems for clients, pay his coaches more and generate more revenue. So he cautiously offered a single semi-private time slot to his existing members as a test of a new service.
In a semi-private program, clients get personalized plans and a coach leads two to six people through their workouts at the same time. The program is priced below PT but above group fitness. The demands on the coach are high.
Erik set his rates at about $65 per person for one session, and he launched a trial program with a simple post to his members. He filled the slot in under an hour.
Over the next years, he slowly expanded his slots. He had to make sure he didn’t overwhelm his coaches or his space, and he had to set clear expectations and policies to ensure clients didn’t turn the growing program into a choose-your-own-adventure rebooking and slot-trading nightmare.
He used new revenue to slowly acquire a little extra gear to perfect the space and make programming and logistics easier.
As of June 2025, the program will gross $15,000 in a slow month and over $20,000 in better months.
Overall, it pumps $200,000 into his gross.
Erik’s coaches earn excellent wages that dwarf industry-standard group-class rates.
And his clients are getting spectacular results (yes, he has training data that proves this).
Mentorship FTW
Erik set this program up with the help of Two-Brain mentors Anastasia Bennett and Daniel Purington, who ensured that he didn’t miss any steps.
You can’t just wave your hands and drop a $200,000 program into your gym.
Try to do that and you’ll make big mistakes. Here are a few very common errors gym owners make with semi-private training:
- They try to sell to the public before current members.
- They struggle to sell the program because they don’t have the required consultative sales process in place.
- They fail to explain how the program solves problems for clients because they don’t publish content often enough.
- They attempt to use semi-private training to fill dead hours in the gym.
- They add too many slots too quickly.
- They put the wrong coaches in place.
- They over-program or make mistakes buying new equipment they don’t need.
- They don’t set up their training space properly.
Those errors are enough to sink a program and prompt someone to say, “Semi-private training doesn’t work in my gym.”
The reality: It will work if you follow the right steps.
Erik Zeyher and Warlock Athletics are the proof.
If you’re a current Two-Brain client and you’re interested in semi-private training, talk to your mentor and make an action plan.
If you don’t work with Two-Brain yet, a mentor can help you set up and sell the services that will allow you to live the life you want. To hear more about that, book a call here.
