Are you searching for a weight loss gym in Sherman TX that actually gets results?

If you’ve been hearing a lot about GLP-1 medications lately — drugs like Ozempic, Wegovy, Mounjaro, or Zepbound — you’re not alone. Millions of Americans are using them to lose weight, and many are seeing real results. But there’s something critically important that most people aren’t being told: without the right exercise program, a significant portion of the weight you lose on these medications won’t be fat. It’ll be muscle.

And losing muscle has consequences that go far beyond how you look. It affects your metabolism, your energy, your balance, and your long-term health.

The good news? This is entirely preventable — with the right fitness program. That’s exactly what we help people do at Solus Fitness in Sherman, TX.

What the research actually says about GLP-1 medications and muscle loss

Semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) work by suppressing appetite and slowing digestion. They’re genuinely effective at reducing calorie intake — but here’s the problem: when your body is in a calorie deficit, it doesn’t just burn fat. It also breaks down muscle tissue for energy.

Research presented at the Endocrine Society’s 2026 annual meeting found that people taking GLP-1 medications became significantly less physically active over time — even as they lost weight. That’s the opposite of what most people expect. Studies also show that without strength training, people on these medications can lose anywhere from 10 to 40 percent of their weight loss from lean muscle mass, not fat.

The American College of Sports Medicine puts it plainly: exercise is essential during GLP-1 treatment to preserve lean mass and protect long-term results.

Why muscle loss matters more than most people realize

Muscle isn’t just about strength or how you look. It’s metabolic currency. Here’s what happens when you lose it:

  • Your metabolism slows down, making it harder to maintain weight loss long-term
  • Your risk of regaining weight — especially fat — goes up significantly when you stop the medication
  • Balance, posture, and joint health all decline, increasing risk of falls and injury
  • Energy levels drop, making it harder to stay active
  • Bone density can decrease, especially in adults over 50

This is especially important for adults over 50, who already face natural muscle loss as part of aging. Combining that with GLP-1-related muscle loss without a strength program is a recipe for long-term problems.

What kind of exercise actually protects your muscle on GLP-1 medications

Not all exercise is equal when it comes to preserving muscle. Walking and cardio are great for your heart, but they’re not enough to signal your body to hold onto muscle tissue. You need resistance training — exercises that put your muscles under load.

The most effective approach combines:

  • Strength training using weights, kettlebells, or bodyweight movements — at least 2-3 sessions per week
  • Functional movements that train your whole body together, not just isolated muscles
  • Adequate protein intake (your coach or nutrition professional can guide you here)
  • Progressive programming that adjusts as your body changes

This is exactly the kind of training we’ve been delivering at Solus Fitness since 2009. Our group fitness classes and personal training programs are built around functional strength and conditioning — the kind of training that gets results and keeps your body strong for the long haul.

You don’t need to be a gym person to start

We hear this all the time: “I’ve never really worked out before.” Or: “I’m not sure I’m fit enough to join a gym.”

Here’s the truth — you don’t have to be fit to start. You just have to start. Every workout we offer is fully scalable, which means our coaches adjust every movement and every weight to match exactly where you are right now. We’ve worked with complete beginners in their 60s. We’ve worked with people recovering from injury. We’ve worked with busy parents who haven’t exercised in years.

What matters isn’t where you’re starting. It’s that you have coaches who know what they’re doing, a community that shows up with you, and a program designed to move you forward safely.
