GLP-1 medications like semaglutide and tirzepatide have changed the conversation around weight loss.
For many people, these medications can make losing a significant amount of weight far more achievable. But there's an important question that doesn't get nearly enough attention:
What are you building while the weight is coming off?
If you're taking a GLP-1, this can be an incredible opportunity to improve more than the number on the scale. Learning how to exercise while taking GLP-1 medications, eat appropriately, and build sustainable habits can help turn a period of weight loss into a healthier lifestyle.
The medication can be a tool. Your goal should be building the body and habits you want to maintain long term.
GLP-1 Muscle Loss: Don't Focus Only on the Scale
When someone loses a significant amount of weight, not every pound lost is necessarily body fat.
Some lean tissue can also be lost during weight loss. Research on GLP-1-based medications has therefore raised important questions about preserving muscle during treatment.
That doesn't mean GLP-1 medications automatically "destroy muscle." The research is more complicated than that, and improvements in overall body composition can still occur.
But it does give you another reason to stop treating scale weight as your only measure of success.
If you lose 40 pounds, you don't just want to become a smaller version of yourself.
Ideally, you want to lose substantial body fat while maintaining as much strength, muscle, and physical function as possible.
Strength Training on GLP-1 Should Be a Priority
One of the most valuable habits you can establish during weight loss is resistance training.
Your muscles need a reason to stick around.
Strength training provides that signal.
