Why Weight Training Matters When You’re on GLP-1 Medications, And Why Physio-Led Sessions Are Ideal

GLP-1 medications such as semaglutide (such as Ozempic®, Wegovy®, Mounjaro® and others) have become powerful tools in helping people manage weight, appetite, blood sugar, and metabolic health. But alongside the benefits, there’s an important consideration that often gets overlooked: muscle loss.

Whether you’re on a weight-loss journey or using GLP-1s for metabolic or diabetes management, protecting your muscle mass is essential for strength, long-term health, and sustainable results. This is exactly where targeted, physio-led weight training can make all the difference.

At Surf Coast Physiotherapy & Pilates, our brand new, upgraded rehab studio and 1:1 physio-led strength sessions offer a safe, private, expert environment to help you stay strong and confident, no matter your starting point, fitness level, or injury history.

Why GLP-1 Medications Can Lead to Muscle Loss

GLP-1s work by reducing appetite, slowing gastric emptying, and helping regulate blood sugar. Because people often eat less on these medications, weight loss can sometimes happen quickly, and not all of that weight comes from fat.

Research shows that up to 25–40% of weight lost on GLP-1 medications can be lean mass, including muscle.

Why this happens:

• Reduced calorie intake means the body draws energy from multiple sources, including muscle tissue.

• Appetite suppression can make it harder to consume enough protein.

• Less spontaneous activity (common due to appetite, energy, and body-weight changes) can reduce muscle stimulus.

• Age, hormones, and pre-existing deconditioning further increase muscle loss risk.

Losing muscle isn’t just about strength, it influences:

• Metabolism (muscle is metabolically active tissue)

• Insulin sensitivity

• Bone health

• Balance and injury risk

• Long-term weight maintenance

The good news? Weight training is the most effective way to counteract this.

So How Does Weight Training Protects Muscle While on GLP-1s?

Strength training does far more than build visible muscle. It sends a strong signal to your body to preserve and rebuild lean mass, even in a calorie deficit.

Key benefits include:

• Reduced muscle loss: Your body is far more likely to maintain or increase muscle mass during weight loss.

• Improved metabolism: More lean mass means a healthier resting metabolic rate.

• Better insulin sensitivity: Muscle is one of the largest glucose-utilising tissues in the body.

• Enhanced ability to keep the weight off: Muscle helps regulate energy balance long term.

• Support for joints and injury prevention: Strong muscles provide stability and load-sharing for bones, ligaments, and tendons.

For people using GLP-1 medications, this isn’t just “nice to have”—it’s essential for healthy, sustainable outcomes.

Why Physio-Led Strength Training Is the Gold Standard

Many people feel unsure where to start with strength training, especially when dealing with pain, pelvic health concerns, past injuries, or fear of doing it wrong.

Our 1:1 sessions take away all the guesswork.

Here’s what makes our approach different:

🔹 Expert, evidence-based programming

As physiotherapists, we understand your medical history, biomechanics, and how to train safely in a calorie-restricted or weight-loss state.

🔹 Rehab and training at the same time

We don’t just “work around” injuries, we actively treat and strengthen them during sessions. Shoulder pain? Low back niggle? Pelvic floor concerns? These can all be addressed while still progressing your strength.

🔹 A private, welcoming studio

With our newly upgraded rehab studio, you can train without feeling self-conscious or overwhelmed. No crowds, no pressure, just a supportive environment curated for your success.

🔹 Subsidised Treatment

Some may be eligible for subsidised sessions on a Medicare chronic disease care plan from your GP for up to 5 sessions per calendar year. Sessions are also rebatable on private health when done with a physio.

🔹 1:1 care with physiotherapists who understand GLP-1 medication needs

We tailor your program around:

• Appetite and energy fluctuations

• Lean mass preservation

• Protein and recovery needs

• Blood sugar responses

• Surgical history or pelvic health considerations

🔹 A focus on consistency and confidence

We build a plan you can stick with long term; safe, structured, and effective.

What We Focus on in Physio-Led Strength Sessions

Your program may include:

• Progressive resistance training

• Functional strength for daily life

• Anti-osteoporosis loading

• Metabolic conditioning for improving insulin sensitivity

• Core and pelvic health strength

• Mobility for joint health

• Injury-specific rehab integrated into the session

We track your progress closely, adjusting week by week so you continue to gain strength safely and sustainably.
