Best Cardio for Weight Loss: What Works on a GLP-1 Journey

Cardiovascular exercise burns calories, supports heart health, and can help preserve muscle during a period of reduced calorie intake — all relevant when you are losing weight on a GLP-1 medicine like Mounjaro (tirzepatide) or Wegovy (semaglutide). The key is understanding what different types of cardio offer, so you can choose what fits your life.

Moderate-intensity steady-state cardio

Activities like brisk walking, cycling, swimming, or using a cardio machine at the gym at a steady pace are often the easiest to sustain. They place less stress on the body and can be done even on days when energy feels lower — something many people on GLP-1 medicines experience early on. Aiming for 150 minutes per week of moderate-intensity movement is a widely referenced general guideline, though your prescriber or doctor is best placed to advise on a target that suits your individual health.

Higher-intensity interval training (HIIT)

Short bursts of harder effort followed by recovery periods can be time-efficient and may support metabolic rate. That said, HIIT is more demanding, and if nausea or fatigue are present — as they can be during dose changes — lower-intensity options are often more practical. Listening to your body is more important than following any fixed programme.

Why cardio alone is rarely the whole picture

Cardio works best alongside strength training, which helps protect lean muscle mass while you lose weight. Relying on cardio alone can make it harder to maintain the metabolic rate that supports long-term progress. The two approaches complement each other well on a GLP-1 journey. It is also worth knowing that some people explore additional support for motivation and behaviour change — including approaches like hypnotherapy for weight loss — though outcomes vary and any such approach should complement, not replace, physical activity and clinical supervision.

Seeing your progress clearly is one of the strongest motivators to keep moving — and GLP Trackr is built to show you the full picture, not just a number on the scale.

The app's weight and body tracking feature logs your weight over time and presents it as a chart, so you can see the trend across weeks rather than fixating on daily fluctuations. This matters for cardio training in particular, because exercise can temporarily affect the scale (through water retention in muscles) even when real progress is happening. Watching the week-by-week trend is far more informative than any single weigh-in.

Alongside that, the daily check-in takes just a few seconds each morning and captures energy levels alongside weight — which means you can start to see patterns between your activity, how you feel, and how your body responds. On days when energy is low, that context helps you make a sensible call about whether a shorter walk makes more sense than a hard session.

You can also set a steps target in the app, making everyday movement — the kind that adds up without requiring a gym — part of your tracked progress alongside any structured cardio. For a broader view of everything shaping your results, the weight loss tracking hub brings together the full range of tools the app offers.

Progress on a GLP-1 journey is rarely linear, and the same is true of any exercise routine. If you have any concerns about what type or intensity of exercise is appropriate for you — particularly if you have existing health conditions — always check with your prescriber or doctor before starting something new. GLP Trackr helps you record your journey and spot your own patterns; it is not a substitute for personalised clinical advice.
