Women’s Fitness Trainer & Nutrition Coach

I’m Kristy—mom of 5 (yes, twins included!), former collegiate athlete, and marathon runner! Fitness has always been part of my life, and in many ways it has carried me through motherhood. But over the years, it has completely evolved. I’ve tried it all—powerlifting, running, group fitness, boot camps, HIIT… but each time, I’d burn out and move on to the next thing. I needed a smarter, more sustainable way to stay fit and feel good. 💡 In 2024, I made a shift: ☑️ Daily steps > running, endless cardio & random workouts ☑️ Short lifts > long, exhausting gym sessions ☑️ Protein & fiber (eating to fuel) > restrictive eating, guilt, & obsessive tracking. ☑️ Sleep & recovery > overtraining & burnout ✨ And everything changed. ✨ Now, as a busy mom of 5 in my 40s, my workouts are short & effective, my nutrition is simple & flexible, and my lifestyle is realistic—because fitness should fit your life, not take over it! I feel strong, lean, and energized—without the overwhelm. This journey led me to create The Lean Lifestyle Method—helping busy women simplify fitness & nutrition for lasting results.

My Own Story

Just over a year ago, I had turned 40 and was feeling completely burned out—exhausted, inflamed, and worn down by the way I was training. So I made a shift: I started strength training 4 times a week for just 30–40 minutes using minimal equipment. I walked more, prioritized protein and fiber at meals, took more rest days, and made 7 hours of sleep a goal. With those simple changes, I lost 5 pounds and felt leaner and stronger than I had in years. Most importantly, it’s been sustainable—and even enjoyable. I look forward to my workouts now because they energize me instead of draining me!
