Core Progression × Vitelize

Better weight loss, where you already train.

As a Core Progression member, you already have the training. Vitelize adds the missing half — physician-guided medical care, metabolic measurement and nutrition — so fat loss protects the muscle you’re building.

Why this pairing works

You bring the training. We bring the medicine.

A prescription mailed to your door is not a program. At Core Progression, the supervised resistance training and body-composition scans that protect lean mass are already part of your routine — Vitelize wraps licensed clinical care and monitoring around them.

One shared record connects your Core Progression coach and your Vitelize clinician, so every lab, dose, session and scan lives in one place.

92% vs 61%Lean mass preserved with supervised resistance training versus medication alone, in published research (Biggs et al., Obesity Reviews 2024).
⅔Roughly two-thirds of weight lost on a GLP-1 alone is regained within a year of stopping (STEP-4, JAMA 2021).

Figures describe published research, not Vitelize outcomes. Individual results vary.
