Fitness after 40 isn't about slowing down. It's about training smarter.
After 40, your body changes — muscle mass drops, joints complain, recovery takes longer, and the workouts that worked at 30 stop working. Fit Over 40 is Underground Gym's flagship approach for adults over 40, under our Stronger After 40 umbrella. It isn't one class or one format: it's a personal plan that can combine private coaching, small group training, and group sessions — matched to your goals, your body, and your schedule.

Strong Again small group training — your own program, coached in a group of no more than 7.
PRIME 30 — 30-minute coached sessions when time is the constraint.
Most members combine two formats. Your consultation decides the mix — and it can change as you progress.
Consultation — a deep dive into your goals, health history, medications, and what's held you back.
InBody scan — body composition facts: muscle, body fat, and where you actually stand.
Movement screening — how your joints and back move today, so training works with your body, not against it.
Your blueprint — you leave with a clear plan and exactly what to do next: which formats, how often, and what we'll measure along the way. Where it helps, nutrition guidance and blood-work/biomarker review are part of the plan.























Strength — muscle is your retirement account: it protects your bones, joints, and independence.
Fat loss that lasts — training plus simple nutrition guidance, tracked with repeat InBody scans.
Energy and mobility — move better, hurt less, keep up with your life.
Joint- and back-safe progress — every exercise coached and adjustable around orthopedic issues.
Underground Gym holds a 4.9-star rating across 114 Google reviews — more reviews than any personal training studio in the Red Bank area.
"Sergei and his staff are experienced, attentive and always encouraging while challenging you, making sure that every student is safely performing each exercise." — Mike Luzio

Our members train with us from Red Bank, Middletown, Rumson, Fair Haven, Little Silver, Shrewsbury, Holmdel, Tinton Falls, and Colts Neck. The studio is at 327 Hwy 35 in Red Bank, with morning sessions from 6 AM and evening sessions through 8 PM.
I'm in my 50s/60s and haven't exercised in years. Is this for me? — Yes — that's exactly who Fit Over 40 is built for. Your plan starts from your screening, not from a template.
How is this different from Strong Again or PRIME 30? — Those are formats. Fit Over 40 is the plan that decides how you use them — and adds the health picture: InBody tracking, nutrition, and blood work where relevant.
What if I have back pain, arthritis, or a replacement joint? — Common here. Training is built around your medical situation and adjusted by your coach every session.
How much does it cost? — It depends on the mix your plan needs. Options are week-to-week with no long contract; your consultation ends with an exact price.
