Your prime isn't behind you. It's 30 minutes.
PRIME 30 is Underground Gym's 30-minute coached workout for adults 40+. Strength and conditioning, led by a coach, in a small group — and every workout is tracked. When a workout comes around again, you see exactly what you did last time and go one better. You compete with your past self, not with anyone else in the room.
Kettlebell training is part of the mix — coached from your first hip hinge.

It's a full workout, not half of one. — PRIME 30 sessions are built to cover strength and conditioning in 30 focused minutes — no standing around, no filler.

Tracked, every time. — Your results are recorded each session, so progress is measured in numbers, not feelings.
It fits a real schedule. — Over 35 sessions a week, from 7 AM to 7:30 PM — before work, lunch, or after.
Coached and capped. — A coach leads every session and adjusts exercises to your body — joints, back, and limitations included.
Consultation — We talk through your goals, health history, and what has or hasn't worked before.
Assessment — An InBody body-composition scan and a movement screening, so your plan starts from facts, not guesses.
Your plan — You get a clear path: the right format, the right schedule, and exactly what to do next. Then we coach you through it, session by session.
















Busy adults 40+ who want to get stronger, leaner, and more energetic but can't give an hour to the gym. Beginners welcome — your coach scales every workout to your level.
