Built for independent trainers.

Already running your own client base but training out of a crowded commercial gym? j+k rents session-based space to a small number of independent trainers. You bring your clients — we provide the environment and the equipment.

No long-term commitment. No revenue share. Just professional space at a fair per-session rate.

Everything you need.

Full Equipment Access

Hammer Strength power rack, Life Fitness machines, kettlebells, cables, resistance bands, dumbbells, mats — everything in the studio is yours to use during your session.

Private Session Environment

Small, intimate studio. No crowded gym floor. Your client gets your full attention in a focused, professional setting they'll appreciate.

Clean, Well-Maintained Space

We keep the studio to a high standard. Equipment is maintained, the floor is clean, and the environment reflects the quality of work you're doing.

Simple Per-Session Rate

Straightforward pricing. No membership fees, no revenue split, no surprises. You keep what you earn.

Simple from day one.

Step 02

We'll walk you through the studio, answer your questions, and make sure it's the right fit. No pressure.

Set Up Your Schedule

Once we're aligned, we'll get you set up in our scheduling system. Book your sessions in advance and we'll confirm availability.

Step 04

Train Your Clients

Show up, do great work. Billing is handled per session — simple and clean. Your clients are yours, your income is yours.

You might be right for this.

  • You're a certified trainer with an existing client base
  • You're tired of training in crowded commercial gyms
  • You want a professional space without the overhead of your own studio
  • You take your craft seriously and want an environment that reflects that
  • You're looking for flexibility — not a full-time employment arrangement
