Become a coach at Underground Strength.
We're looking for experienced trainers who care about real coaching — not just counting reps. If you want a gym that values quality over quantity, you might belong here.
What this role looks like.
Coach Real Sessions
Run personalised small-group and 1-on-1 strength sessions with members who are invested in their training. No drive-by check-ins — actual coaching.
Build Client Relationships
You'll know every member by name, understand their goals, and track their progress. This is long-term coaching, not revolving-door PT.
Program With Purpose
Work within a proven strength-focused framework. Squat, bench, deadlift, overhead press — the fundamentals done well, with room for your coaching style.
Work in a Small Team
We're a tight crew, not a franchise floor of 40 trainers. You'll be part of a coaching team where your input matters and your development is prioritised.
Grow as a Coach
Regular feedback, mentorship, and the space to develop your craft. We invest in people who want to get better at what they do.
More than just a floor space.
Supportive Coaching Environment
Work alongside coaches who share knowledge, not egos. We lift each other up — literally and figuratively.
Clients Who Actually Show Up
Our members are committed. They train consistently, follow programming, and genuinely want to improve. That makes your job rewarding.
Programming Support
Access to proven program templates and mentorship on periodisation, progression, and adapting to individual needs.
Small Team, Not a Franchise
No corporate politics. No forced sales targets on supplements. Just coaching, community, and a gym that runs the way it should.
Freedom Within a Framework
Coach your way within our proven system. We don't micromanage your style — we trust you to bring your coaching voice to the floor.
A Gym That Gives a Damn
We care about our members' outcomes, our coaches' growth, and building something that actually makes a difference. That's not a tagline — it's how we operate.
Hey! It's Lenny, the owner of Underground Strength. I saw something that bothered me in these gyms. Many clients were lost in the crowd of class-based studio gyms, running endlessly on treadmills without personalized attention or guidance. So I created Underground Strength — a gym that prioritized strength and muscle building outcomes while providing individualized coaching and support. I look forward to hearing from you.— Lenny, Founder of USG
