The smarter way to use GLP-1s

Lose fat. Preserve muscle. Protect your metabolism. Perform better.

PAIR YOUR MEDICATION WITH A SYSTEM

GLP-1s work. But how you use them matters.

Medications like semaglutide (Ozempic) and tirzepatide (Mounjaro, Zepbound) can be powerful tools for weight loss. But appetite suppression, rapid weight change, and under-fueling can carry unintended consequences, especially for people who care about strength, energy, and long-term health.

A doctor-led team that helps you lose weight while keeping muscle, strength, and energy

There is no need to risk your healthspan or performance while losing weight. We coordinate medical oversight, nutrition strategy, strength training, and body composition tracking so your results feel better and hold up over time.

Who is this for?

  • You’re already taking a GLP-1 and want real monitoring—not just a prescription
  • You want to lose weight without losing muscle, strength, or momentum
  • You want one coordinated team (clinician + RD + trainer)
  • Not on a GLP-1, but curious about starting? Book a free consultation

What we monitor

Muscle retention
With GLP-1 medications, the goal is not just weight loss but preserving lean muscle mass, which supports metabolism, strength, and long-term health. Rapid weight loss can lead to muscle loss if not monitored. Tracking lean mass ensures fat loss is prioritized while strength and metabolic health are protected.

How we test:
Monthly dexa scans
Smart fueling (not just less food)
Appetite suppression can sometimes drive excessive or inappropriate caloric restriction. Monitoring intake and body composition helps identify underfueling early, which can impair metabolism, hormone health, training capacity, and recovery. By tracking these signals, we ensure weight loss is achieved safely and sustainably rather than at the expense of health or performance.

How we test:
Monthly dexa scans, before & after blood labs
Energy + training quality
Fatigue and declining training quality can signal underfueling or poor recovery. Monitoring performance and training output helps catch these issues early, before strength, muscle, and metabolic health are compromised. This allows weight loss to continue safely while maintaining energy, consistency, and long-term results.

How we test:
Active monitoring via clinicians and in-person personal trainers
Mood + mental well-being
Changes in mood or emerging depressive symptoms can be an early sign of underfueling, hormonal disruption, or excessive dose escalation. Monitoring mental and emotional health helps identify these risks early, allowing adjustments that support both effective weight loss and overall well-being.

How we test:
Active monitoring via clinician feedback
Nutrient coverage
Reduced appetite and lower food intake can increase the risk of micronutrient deficiencies. Monitoring labs and nutrition helps identify gaps early, preventing issues that can affect energy, mood, immunity, and long-term health while supporting safe, sustainable weight loss.

How we test:
Frequent dietitian check-ins
Strength protection
Loss of strength can signal muscle loss, underfueling, or inadequate training stimulus. Monitoring strength allows us to detect these issues early and adjust nutrition, dosing, and training so weight loss does not come at the expense of performance or long-term health.

How we test:
Monthly in-person strength exams

How it works

2.5 hours, hundreds of insights, twice per year and tracked over time.

01

Mobility & Stability

After a dynamic warmup we’ll use functional movement and balance tests to measure your range and quality of motion as well as your core stability and muscle control.

02

Strength & Power

Next, we measure your ability to produce force and how quickly you can apply it. We use force plates and targeted exercises to identify imbalances and guide your training.

03

Aerobic Function

To identify your aerobic and anaerobic thresholds, you’ll do a Lactate Ramp test. You’ll move through stages on a treadmill or bike, with a quick finger prick after each.

04

Aerobic Capacity

Finally you’ll roll right into your VO2 max test, which measures your aerobic capacity (VO₂ max) or how efficiently your body uses oxygen during intense exercise.
