Muscle-Preserving
Physician-prescribed GLP-1 therapy + supervised gym training at Core Progression. The only weight loss program that guarantees results AND preserves your muscle.
Every telehealth clinic will sell you a GLP-1 prescription and send you home. Here's what they won't tell you.
On GLP-1 alone, up to 40% of what you lose is lean muscle mass. You're not getting lean — you're getting weak.
Two-thirds of weight lost on GLP-1 returns within a year. And when it comes back, it comes back as fat — not the muscle you lost.
We pair your GLP-1 prescription with supervised resistance training. You lose the fat. You keep the muscle. And we guarantee 10 lbs in 30 days or you don't pay.
No waiting rooms. No guesswork. Just a physician-guided system that works — or you don't pay.
Take a 2-minute quiz and book a free call with our clinical team. We'll assess your goals, health history, and eligibility.
Your physician builds a personalized GLP-1 prescription plus a resistance training protocol tailored to you.
Begin supervised sessions at Core Progression Elite Personal Training. Your trainer and physician work together.
Regular body composition check-ins, dose adjustments, and training progressions. We measure what matters — not just the scale.
Hims, Ro, Rocky — they'll prescribe the medication and disappear. Here's what you actually get.
