Online Coaching for Working Men
A done-for-you system for men who work full-time and are tired of carrying stubborn belly fat, built to strip it off and rebuild your health without counting calories or restrictive dieting, and without blowing up the schedule you've already maxed out.
About Me
My name is Bobby O'Brien, and I'm a NASM Certified Personal Trainer, Certified Nutrition Coach, and Corrective Exercise Specialist through the National Academy of Sports Medicine. I'm the founder and head coach of Optimize Lives, where I help working men lose stubborn belly fat and optimize their health without counting or restricting a single calorie.
I understand the frustration of trying unsustainable methods that never deliver lasting results. That frustration is what drove me deeper than most coaches ever go. My obsession with health optimization led me to study under my father, a licensed medical doctor with over 40 years of clinical experience, who served as my mentor and advisor. For five years I studied anatomy, physiology, insulin regulation, and circadian biology under his mentorship.
That combination is the whole point: certified, professional coaching paired with a clinical, physiology-based foundation most online coaches simply don't have. The knowledge I gained working alongside him is passed directly to my clients through a personalized, hormonal-based approach that addresses the root cause of weight gain, not the symptoms.
I work with busy men who've prioritized their careers for so long that their health took a back seat. They sit most of the day, carry demanding schedules and real responsibilities, and struggle with stubborn belly fat that feels nearly impossible to lose and keep off. Through my Health Optimization Program, I give them a fully customized nutrition plan, a personalized training program, and an accountability system designed to lose fat and optimize health, with proactive check-ins, one-on-one support, and the resources to maintain it for life.
Work With MeThe Method
If you've tried counting calories, cutting carbs, caloric deficits, macros, or portion control, you already know two things they have in common: they feel like torture, and they never address why the weight came on in the first place. We do the opposite. We fix the root cause using a hormonal, physiology-first approach.
Stubborn belly fat is a hormonal problem before it's a calorie problem. We regulate insulin and the hormones that drive fat storage, so your body stops holding fat around your midsection, and you eat more real food, not less, while it happens.
Your sleep, stress, and daily rhythm quietly control your metabolism. We install a circadian protocol that lowers stress, improves recovery, and gets your physiology working for you, something most men who sit at a desk all day never address.
Long hours at a desk wreck posture, mobility, and movement quality. Corrective exercise assessments rebuild how you move so training feels good and stays sustainable, engineered around a demanding schedule, not a bodybuilder's.
We start with a 1-on-1 onboarding call where we fully customize your meal plan and map exactly how we'll address the root cause of your weight gain.
You get a personalized nutrition plan, training program, and full accountability system to lose belly fat sustainably, no counting, no restricting.
I proactively check in to keep you consistent, with ongoing 1-on-1 calls so you have everything you need to hit your goal and keep it.

See If You're a FitReal Men. Real Results.
These are working men with demanding jobs who lost stubborn belly fat and kept it off, and ate more food doing it. Here are their stories, in their words.
Network Engineer
Steve wanted to lose 40 lbs and his belly fat before his wedding. He'd worked with an in-person trainer and counted calories, but never saw sustainable results. He lost 12.4 lbs in his first 9 days, 30 lbs in two months, and 40 lbs in four months, losing all his belly fat while managing a demanding schedule. He even re-measured for his wedding tux and had dropped almost 3 inches off his waist.
HVAC Technician · 60-hour weeks
Chris worked 60-hour weeks and had tried restrictive diets and calorie deficits without ever finding something sustainable. He wanted a plan that fit his schedule and finally broke his plateau. He started at 236 lbs and lost 36 lbs in 3.5 months, eventually reaching 183, a flat stomach and body fat gone across the board. He's sustaining it now without further coaching.
Sales
Joe wanted to lose stubborn belly fat and break a weight-loss plateau after years of 3-month restrictive diets and quick-fix pills. He lost 14 lbs his first month and 20 lbs of body fat in two months, getting down to the low 190s and eliminating his belly fat. Once we stopped working together, his weight hasn't moved since.
IT Sales Professional
Dion wanted to lose belly fat and overall body fat while managing a demanding career. He'd tried restrictive diets and brutal cardio that felt like torture. He lost 12 lbs in his first month, with zero cardio, on a plan that fit his career lifestyle perfectly. In his words: "I look forward to it every morning."
Business Owner
Brian runs his own business and had tried cardio-heavy programs and plant-based dieting without addressing his rapid weight gain. He lost 10 lbs in his first three weeks, shed almost all his stubborn belly fat, increased strength in 90% of his lifts, and gained real muscle. "I am feeling focused and stronger, thanks Bobby. You make a difference in people's lives."
College Professor
At 265 lbs, Hollis wanted to lower his blood pressure, cut his heart-disease risk, and lose body fat while managing a demanding career and travel across Europe. He lost 36 lbs in 3.5 months and finally found an approach that was sustainable for his life.
Teacher · Long hours at a desk
Michael started at 238 lbs and lost 32 lbs in under 3 months, getting a flat stomach, moving better, and feeling more confident. Even certified to teach nutrition himself, he said it helped him more than any trainer he'd worked with before.
…and many more: Wally down 4.5 lbs in 3 days · Erik down 20 lbs in 2 months · Sonny down 17 lbs in his first month · Gabe 7 lbs from his goal in 2 weeks. Same story, every time.
You've seen what they get and the proof it works. The only question left is whether you're ready.
I'm Ready to StartQuestions
No. The entire approach is built so you don't count or restrict a single calorie. We address the hormonal root cause of weight gain, which means most clients actually eat more real food than they did on past diets, and lose more fat doing it.
That's exactly who this is built for. Every client featured here is a working man with a demanding schedule. Your training, nutrition, and recovery are engineered around your real week, and the corrective and circadian protocols specifically counter the effects of sitting all day.
Most coaches offer certified training. Few pair it with a clinical, physiology-based foundation. I studied for five years under my father, a medical doctor with 40+ years of clinical experience, in insulin regulation, circadian biology, and corrective exercise. You get certified coaching and that deeper physiological approach in one program.
Because the methods you've tried, counting, deficits, macros, portion control, only ever managed symptoms. They never fixed why the weight came on. We target the root cause, which is why these results last after coaching ends.
It varies by person, but clients commonly see meaningful change quickly. Several lost 10 to 12 lbs in their first few weeks. The bigger goal is sustainable fat loss you keep for life, not a crash that rebounds.
You get one-on-one onboarding and ongoing calls, direct one-on-one messaging between calls, meal reviews, and proactive check-ins from me. You're never left to figure it out alone.
Your programming is customized to the equipment and access you have. We build the plan around your situation, not the other way around.
