If you're over 40 and the weight loss approach that used to work has stopped working, you're not imagining it. At Underground Gym in Red Bank, we help women through perimenopause and menopause lose weight and keep their muscle — with strength training, nutrition guidance and a coach in every session. No extreme diets. No burnout cardio. Just a plan built around the body you have now.

It gets harder because hormone changes and muscle loss slow your metabolism, while busy schedules and poor sleep make habits harder to keep. The diet and workouts that worked at 30 often aren't enough anymore.
Mayo Clinic explains that lower estrogen around menopause is linked to muscle loss and more fat stored around the midsection, and that less muscle means fewer calories burned, even at rest. Sleep problems and hot flashes can also make healthy routines harder to stick to.
Yes — a strength-first program can help you lose weight and keep muscle through perimenopause and menopause, even when dieting alone has stopped working. We coach the training, nutrition habits and recovery; we don't treat hormones or medical conditions.
We work alongside your doctor, not instead of them. If you're on medication or managing a health condition, tell us at your consultation and we'll build your plan around it.
Strength training is the better foundation, because it helps you lose weight while protecting the muscle that keeps your metabolism up. Cardio still has a place in your plan, just not as the main event.
Mayo Clinic recommends strength training at least twice a week for midlife weight gain. In an 18-month Wake Forest University study of adults in their 60s, people who added weight training to a reduced-calorie diet lost slightly more weight than those who added walking — and a much smaller share of it was muscle:
| Approach | Weight lost | Share of weight lost that was muscle |
|---|---|---|
| Diet only | about 10 lb | about 16% |
| Diet + walking | about 16 lb | about 20% |
| Diet + weight training | about 17 lb | about 10% |
You keep muscle by lifting regularly, eating enough protein and losing weight steadily instead of crash dieting. Those three things sit at the core of every plan we build.
A study reported by Harvard Health found that older adults who added resistance training while losing weight kept more muscle and gained more strength than those who did aerobic exercise alone. That's why every program at Underground Gym starts with coached strength work, sized to your body and your joints.
Every client starts with a full assessment, not a workout. We look at your body composition, how you move, and what your health history says — then your coach builds your personal blueprint: the training, nutrition guidance and recovery priorities that make up your Stronger After 40 plan.
“Women after 40 go through natural hormonal changes that make it harder to keep healthy body metrics and weight. So the tools have to change: nutrition habits, activity habits and recovery patterns all need adjusting, guided by the right biomarker analysis. We don't experiment on our clients. We give a proven plan of action that fits into your life, and we see it work again and again for women who stick with it.”
Sergei Karaliou / Founder & Head Coach
We measure your body composition, how you move, and how stress, sleep and lifestyle are affecting you, so your plan starts from facts, not guesses. As you go, you see what's actually changing — muscle, body fat and strength — not just the number on the scale.
Your assessment includes an InBody body composition scan, and we repeat it so you can track muscle and body fat over time. If you're searching for an InBody scan near you in Red Bank, it's part of your free consultation.
Yes — you can work with a personal trainer one-on-one, or train in a small group with other women and men over 40 at a lower cost. Your free consultation is where we decide which fits you.
Private coaching gives you maximum attention. Small group training adds accountability and the energy of training with people at the same stage of life. See all our personal training options in Red Bank — and the Fit Over 40 page.
