Health Through Strength.

Physician-led concierge coaching for women to achieve fat loss, sustainable strength, and long-term metabolic health.

Personalized

Your plan is built around your unique body, history, lifestyle, preferences and goals. We ensure that the approach fits you, not the other way around.

Evidence-Based

Every recommendation is grounded in physiology, up-to-date research, and clinical experience. Decisions are made using evidence and data, not trends or guessing.

Results-Focused

The goal is measurable progress in body fat percentage, muscle mass, strength, and metabolic health. The plan is adjusted strategically to support consistent progress.

“If you’re working with Dr. Felber, you’re getting someone who knows the body inside out. She can actually help you get stronger and healthier for the long haul.“

— Dr. Goldberg, Pediatric Emergency Physician and Medical Director of Emergency Management, CHLA

Dr. Rachel Felber

I spent over 10 years practicing emergency medicine, treating the consequences of preventable disease. Over time, I realized the most meaningful care happens long before the ER. Today, I help people build health proactively — through strength, nutrition, and sustainable habits.

— Elizabeth

I HIGHLY recommend Rachel Felber as a trainer and general wellness coach! I am a 59 year old woman who recently had to give up running due to excessive cartilage loss in my left knee. I had known for several years that weight training was very good for us, especially as we age, but had always been reluctant (scared? stubborn?) and more of a cardio sort. I heard about Rachel from a friend/colleague and decided to sign up for a term with her. Holy cow am I glad I took the plunge! Rachel has made weight training exciting and rewarding and I feel strong and fit and healthy! Indeed, I signed up again when my term was up and I will do it again after this term. Rachel is the BEST!!!”

— Amanda

Frequently Asked Questions

Who is this coaching for?

This coaching is designed for women who want to improve body composition, strength, bone density, metabolic health, and overall health in a sustainable way. Many clients are busy professionals who want clear guidance that fits real life, not rigid rules or extreme approaches.

What makes working with Dr. Felber different from other coaching programs?

This is physician-led coaching grounded in science and data, not trends. Programs are individualized based on your body, health history, goals, and response over time, with an emphasis on strength, balanced nutrition, and long-term health rather than short-term fixes.

I’m currently taking a GLP-1 medication. Can I still work with you?

Absolutely. For individuals using GLP-1 medications, preserving muscle while losing weight is essential. Coaching focuses on strength training, adequate protein, and lifestyle strategies that support fat loss while protecting lean tissue and long-term metabolic health.

Is your coaching HSA/FSA eligible?

Our coaching services may be eligible for HSA or FSA reimbursement, depending on your plan. We recommend checking directly with your provider to confirm coverage.

Is coaching done in person or online?

All coaching is done fully online, allowing for flexibility while still providing a high level of personalized support and oversight.

Do I need to have prior experience with strength training?

Not at all. Programs are tailored to your current fitness level and experience – whether you’re a total beginner, looking for more structure to take things to the next level, or navigating changes in your body and needing a different approach to get results.

How do I get started with 1:1 coaching?

The first step is to complete a brief application. There is no obligation or commitment. The application helps determine whether this is a good fit, and if so, you’ll be invited to schedule a call to discuss your goals and next steps.
