Type 2 diabetes is becoming increasingly common, and you might know someone living with it. We often hear about the importance of weight loss and diet in reducing risk, and rightly so. But there’s another tool that is just as important, and often more achievable: exercise.
One of the challenges with the initial advice is that it can feel overwhelming. Being told to lose weight, completely change your diet, and overhaul your lifestyle can seem impossible; it is a difficult thing to do. But the encouraging news is that even if that approach is hard, just focusing on exercise can make a meaningful difference.
When you exercise, particularly when you include strength training, your muscles become better at using glucose from the bloodstream. This helps lower blood sugar levels and improves insulin sensitivity, which is a key factor in preventing type 2 diabetes. In simple terms, your body becomes more efficient at managing sugar.
Strength training is especially effective because muscle tissue acts like a storage site for glucose. The more muscle you have, and the more you use it, the better your body is at keeping blood sugar under control. This is one of the reasons why even modest improvements in strength and fitness can have a big impact on long-term health.
Cardiovascular exercise, such as walking, cycling or swimming, also plays an important role. Regular movement helps your body process energy more effectively and supports overall metabolic health. It doesn’t need to be extreme — consistent, moderate activity is enough to bring benefits.
Of course, this isn’t to say that diet and weight don’t matter. They do. Carrying excess weight, particularly around the abdomen, increases the risk of developing type 2 diabetes, and improving nutrition can significantly reduce that risk. But it’s important to recognise that exercise is not just an optional extra; it is a powerful intervention in its own right.
For many people, starting with movement is the most realistic first step. It builds momentum, improves energy levels, and often leads to better choices in other areas without forcing them.
The key message is this: you don’t have to be perfect to make progress. Just start, anything will do and then move a little bit more, start some strength training. This is where a personal trainer, such as myself, can help. You’ll be shown an achievable route to achieve success.
