About The Optimization Lab
This is the private app for OptiLab coaching clients. If you're working with me, this is where your whole plan lives. WHAT'S INSIDE Your protocol, laid out by day Every supplement and every item in your plan, with the amount, the timing, and how to take it. Morning, pre-training, with meals, before bed. You open it and you know exactly what today looks like. Your phases Your plan runs in phases. You can see the one you're in right now, what's coming next, and what we've already knocked out. If a training block and a protocol phase are running at the same time, you'll see both side by side. Weekly check-ins Your next check-in sits right on the home screen. Weight, photos, sleep, energy, training, digestion, how the week actually went. Send it in, I review it, and you get your adjustments back. Training Your program day by day, with your exercises, sets and notes. Log what you did so we're both looking at the same numbers. Nutrition Your calorie and macro targets for the phase you're in, plus the structure around them. Labs and bloodwork Upload your results, see your testing schedule, and know when your next panel is due. Bloodwork drives a lot of the calls I make, so it lives right next to the rest of your plan. Library The education that goes with your plan. Lectures, guides and resources so you understand the reasoning behind what you're running. Performance League See how your consistency stacks up. Show up, hit your check-ins, stay on plan. WHO THIS IS FOR This app is for active OptiLab clients only. You'll need the login you get when you start coaching with me. If you're not a client yet and you want to be, apply through the OptiLab website. HOW I COACH I work with physique athletes, competitors in contest prep, and people who just want to look, feel and perform better. Everything's individual. It's built from your bloodwork, your check-ins and how your body actually responds, and it gets adjusted week to week. This app is where all of that comes together, so you always know what you're doing today and why. A NOTE ON YOUR HEALTH Nothing in this app replaces your doctor. Keep your physician in the loop on anything medical, and tell me about any changes to your health or medications.
