Weight Lifting for Weight Loss on a GLP-1 Journey

When the body loses weight — regardless of how — there is a natural tendency to lose some muscle alongside fat. Resistance training helps counter this by signalling the body to retain and rebuild muscle tissue, which in turn supports a healthier metabolic rate over time. Many people find this particularly useful on a GLP-1 journey, where reduced appetite can mean eating less overall.

Cardio versus weight lifting for weight loss

Both cardio and resistance training have a role to play, and most people benefit from some combination of the two. Cardio tends to burn more calories in a single session, while weight lifting builds and preserves muscle that keeps your metabolism working more efficiently at rest. Research consistently suggests that a combination approach — rather than one or the other — tends to produce better body composition outcomes over time. Which balance suits you best is worth discussing with your prescriber or doctor, especially if you have any health considerations.

Weight lifting for weight loss: what the evidence suggests

Studies show that people who incorporate resistance training during a period of weight loss tend to retain more lean muscle mass than those who rely on diet or cardio alone. For people on a GLP-1 medicine, where appetite suppression can lead to a significant reduction in calorie intake, prioritising protein alongside lifting is commonly recommended by healthcare professionals to protect muscle. General educational guidance suggests aiming for adequate protein at each meal, though your specific targets should be discussed with your prescriber or a registered dietitian.

A note for those new to resistance training

You do not need a gym membership or heavy barbells to begin. Bodyweight exercises, resistance bands, and light dumbbells all count. Many people find starting with two to three sessions per week, focusing on compound movements that work multiple muscle groups, is a manageable entry point. If you are unsure where to start or have any health conditions, your healthcare professional can point you toward appropriate guidance.

You may also find it helpful to read about hypnotherapy as a complementary weight-loss tool and how other approaches — including what to know about Mounjaro for weight loss — fit into the bigger picture.

Seeing progress in the gym and on the scale is far more motivating when you have a clear record of where you started. GLP Trackr's weight and body tracking feature lets you log your weight and measurements over time, turning what can feel like slow, invisible change into a visible, week-by-week transformation you can actually see.

Beyond the scale, the app's daily check-in captures energy levels, mood, sleep, and how your appetite feels — all of which shift as you build a training habit alongside your medication. Many people find that tracking energy and sleep helps them spot patterns: for example, noticing that rest days feel very different from training days, or that protein intake on lifting days correlates with how they feel the next morning. These are exactly the kinds of insights worth bringing to your next prescriber appointment.

The insights and analytics dashboard goes a step further, surfacing correlations across your logged data — weight, food, activity, mood — so you are not just collecting numbers but understanding what is actually moving your results. If progress stalls, the plateau forecast feature helps you identify when and why, rather than guessing.

It is worth noting that progress on a GLP-1 medicine is rarely perfectly linear, and the scale alone does not capture changes in body composition. Tracking measurements alongside weight gives a much fuller picture of what resistance training is doing for you. You can also explore how other factors interact with your journey by reading about statins and weight loss considerations.

A reminder: any questions about your exercise capacity, medication, or how training fits your personal health situation should always go to your prescriber or doctor — they know your full history and are best placed to advise you.
