GLP-1s (glucagon-like peptide-1 receptor agonists) are being talked about everywhere right now — often as a way to speed up results.

But a more helpful question might be:

​
​ How do we support the body while it’s changing?

Hi Reader,

If you’re like me, you may be noticing more and more conversations about GLP-1s in your media feed, your social circles, and even major advertising campaigns. These medications—originally developed for diabetes and metabolic health—are now part of mainstream culture.

And lately, they’re being framed less as a medical treatment and more as a strategy.

A shortcut.
A tool.
A fitness “accelerator.”

That framing caught my attention.

So I slowed things down and took a closer look at the research, specifically asking:

What I found was both reassuring and clarifying.

GLP-1 medications are highly effective at reducing appetite and supporting weight loss. In many cases, they outperform lifestyle interventions alone—at least in the short term.

But weight loss isn’t the same as physical fitness.

GLP-1s are not designed to build muscle, improve strength, increase cardiovascular capacity, or enhance movement quality. They influence appetite and metabolism—not physical function.

This is where exercise becomes essential.

When weight is lost, some muscle loss almost always follows. Muscle is not just about aesthetics—it’s what allows us to move with confidence, maintain balance, protect joints, and stay independent over time.

Strength-focused exercise gives the body a reason to preserve muscle during weight loss. It also plays a critical role in long-term maintenance, especially when GLP-1 therapy is adjusted or discontinued.

The research consistently shows that people who include regular movement—particularly resistance training—tend to maintain their results more successfully over time.

GLP-1s may help open the door.
Exercise helps you stay there.

And this is where I think we need to pause and reframe the conversation.

A more helpful question might be:

The issue isn’t the medication itself. It’s how it’s framed.

GLP-1s become hype when they’re positioned as a replacement for movement or a guarantee of long-term success. Rapid weight loss without attention to strength, recovery, and fuelling can actually undermine function rather than enhance it.

Exercise does something medication can’t. It builds capacity. It supports confidence. It helps people trust their bodies again—especially during periods of change.

That’s why muscle health matters so much in this conversation.\

If you or someone you know is navigating GLP-1 therapy and want support that prioritizes strength, function, and long-term health, Movement Momentum is my 1:1 program where we focus on preserving muscle, supporting strength, and adapting exercise to your body—right where it is today.

We work with the body, not against it.

Stay well and happy moving,

Lisa

PS: GLP-1 medications change appetite. Exercise protects muscle. Both matter—but they do different jobs.
