If your GP has told you to “move more” but hasn’t told you how, you’re not alone. Exercise is one of the most powerful tools available for managing Type 2 diabetes, but getting started without guidance can feel overwhelming, and getting it wrong can actually make things harder.
This guide walks you through what the evidence says, what types of exercise work best, how to exercise safely when your blood sugar is unpredictable, and when it makes sense to work with a clinician rather than go it alone.
Why exercise matters so much for Type 2 diabetes
Type 2 diabetes is a condition of insulin resistance. Your cells don’t respond efficiently to insulin, so glucose builds up in the bloodstream. What most people don’t realise is that muscle contraction is one of the only ways the body can take up glucose without insulin.
When you exercise, your muscles absorb glucose directly from the blood. This happens during the session itself and continues for hours afterwards, improving insulin sensitivity for up to 24–48 hours after a single bout of exercise. Over time, regular exercise can lead to meaningful reductions in HbA1c; the key marker of long-term blood sugar control.
The effect isn’t trivial. A well-designed exercise program can reduce HbA1c by 0.5–1.5% in the short term and by much more in the long term, which is comparable to adding a second glucose-lowering medication. The difference is that exercise also improves cardiovascular health, body composition, blood pressure, mental health and mobility, none of which a tablet does.
What type of exercise is best?
There’s no single “best” exercise for Type 2 diabetes, the research supports a combination of aerobic exercise and resistance training, and the two work differently.
Aerobic exercise (walking, cycling, swimming) improves cardiovascular health and has an immediate glucose-lowering effect. Even a 10–15 minute walk after meals can noticeably reduce post-meal blood sugar spikes.
Resistance training (weights, resistance bands, bodyweight exercises) builds muscle mass. More muscle means more glucose storage capacity and better long-term insulin sensitivity. For people with Type 2 diabetes, resistance training is often underused, but it’s arguably the more important of the two for long-term metabolic health.
The current evidence-based guidelines recommend:
- At least 150 minutes of moderate aerobic activity per week (spread across most days)
- 2–3 resistance training sessions per week targeting major muscle groups
- No more than 2 consecutive days without activity. Gaps longer than this reduce insulin sensitivity meaningfully
You don’t need to hit all of this on day one. The point is to give you a direction, not to overwhelm you.
How to get started safely
Starting exercise with Type 2 diabetes is safe for most people, but there are a few things worth knowing before you begin.
Check with your Exercise Physiologist first if:
- Your HbA1c is above 10%
- You have cardiovascular disease, neuropathy or retinopathy
- You’re on insulin or sulfonylureas (medications that can cause hypoglycaemia during exercise)
- You haven’t exercised in a long time and have other health complications
Start low and build gradually. Walking is genuinely excellent. Start with 10–15 minutes after meals, which targets blood sugar at its peak. Build to 30 minutes over several weeks. Intensity matters less than consistency early on.
Monitor how your body responds. If you’re checking your blood glucose, test before and after exercise when you’re first starting, especially if you’re on medications. This isn’t about anxiety; it’s about learning how your body responds so you can eventually stop worrying about it.
Stay hydrated. Dehydration concentrates blood glucose. Drink water before, during and after exercise.
Don’t exercise if your blood glucose is above 15 mmol/L and you’re feeling unwell, this can indicate your insulin is insufficient and exercise may worsen the picture. Check with your diabetes care team if you’re unsure.
The problem with generic advice
“Walk more” and “join a gym” are well-meaning but incomplete advice for someone managing a chronic condition. Here’s why generic exercise guidance often falls short for people with Type 2 diabetes:
It doesn’t account for your medications. Some diabetes medications (particularly sulfonylureas and insulin) can cause hypoglycaemia during or after exercise. Knowing how to adjust and when to eat requires clinical input, not a YouTube video.
It doesn’t account for comorbidities. Many people with Type 2 diabetes also have cardiovascular disease, osteoarthritis, obesity, neuropathy or chronic pain. The wrong exercise at the wrong intensity can aggravate these conditions. The right exercise, properly prescribed, addresses all of them together.
It doesn’t provide progression. A program that works in week one won’t be the right program in week twelve. Good exercise prescription is adaptive, it changes as you improve.
When to see an Exercise Physiologist
An Exercise Physiologist is a university-trained allied health clinician who specialises in prescribing exercise for chronic disease and injury. This is not a personal trainer, it’s a clinician who works from your pathology results, medical history and current medications to design a program that’s safe, targeted and measurable.
At Beachside EP in Mordialloc, we see people with Type 2 diabetes regularly, many of whom have never exercised before, or who’ve tried and stopped because nothing seemed to help. A few things we do that a gym can’t:
- Review your HbA1c, blood pressure, pathology results and medication list before designing your program
- Coordinate with your GP and Diabetes Educator so your exercise, nutrition and medication management are working together
- Track your results in real numbers weight, body composition, blood glucose trends, functional capacity, not just how you feel
- Adjust your program as you improve, so you’re always working at the right level
- Help you understand what your CGM data is telling you about how exercise affects your glucose
You don’t need a GP referral to book, though a referral under a Chronic Disease Management (CDM) plan can give you up to 5 Medicare-subsidised sessions per year, a significant reduction in out-of-pocket cost. See our pricing page for a full breakdown of what sessions cost and how funding works.
What results are realistic?
People often ask how quickly they’ll see results. The honest answer: it depends on where you’re starting from, but meaningful changes happen faster than most people expect.
Here’s what’s realistic within the first 3–6 months of a well-designed program:
- HbA1c reductions of 0.5–1.5% often enough to reduce or delay medication escalation
- Improved insulin sensitivity often measurable in your blood glucose trends within weeks
- Reduced post-meal spikes especially with consistent post-meal walking
- Improved body composition muscle gain and fat loss, which reinforces the metabolic benefits
- Lower blood pressure and resting heart rate
- Better energy, sleep and mood less talked about, but consistently reported
At Beachside EP, our diabetes program clients have seen an average 18% improvement in HbA1c. These aren’t exceptional cases, they’re people who showed up consistently and followed a structured plan.
The bottom line
Exercise is not optional in Type 2 diabetes management. It’s one of the most effective interventions available and unlike medication, the side effects are almost entirely positive.
If you’ve been told to exercise more but haven’t been given a real plan, that’s not a motivation problem. It’s a prescription problem. The right exercise, properly designed for your condition and health history, makes a genuine difference.
If you’d like to know exactly where to start, book an initial assessment with our team in Mordialloc. We’ll review your situation, explain what’s appropriate for you, and build a program from there. No referral needed, and no obligation after your first session.
