Welcome

Welcome to B. Lilly Strength & Longevity

Stronger Bodies. Empowered Lives. Every Stage of Life.

Hi, I'm Brenda Lilly — a certified personal trainer and longevity coach based in Allen, Texas. I work with men and women of all ages and fitness levels, from driven adults in their mid-20s to active clients in their 80s who refuse to slow down.

My approach isn't one-size-fits-all. It's built around you — your goals, your history, your body, and your life. Whether you're just starting out, coming back from an injury, managing the realities of getting older, or simply ready to feel stronger and more capable, I'll meet you exactly where you are.

As an ISSA-certified fitness professional, I hold seven specialized credentials — including Senior Fitness, Corrective Exercise, Pilates, Nutrition, and Group Fitness — plus TRX certification from TRX Training. That depth of training means I can handle the complex, layered needs that most trainers aren't equipped for.

With 20 years of leadership and transformation experience from Fortune 100 companies like Collins Aerospace and Raytheon Technologies, I bring a level of structure, accountability, and results-driven thinking to my coaching that most trainers simply can't offer.

I offer both private 1-on-1 sessions and small group training — so whether you prefer the focused attention of individual coaching or the energy of a group setting, there's a place for you here.
