Learning to lift weights or becoming comfortable in the pool can open the door to a more active life. For people with prediabetes or type 2 diabetes, that movement can also help improve blood sugar control. Regular activity is an important part of preventing or delaying type 2 diabetes and managing it after diagnosis. CDC diabetes guidance.
At One with the Water, we want people to feel capable of taking that first step. Understanding what happens inside your body can make the effort feel more meaningful.
Insulin is a hormone made by the pancreas that helps glucose move from your bloodstream into cells for energy. With insulin resistance, muscle, fat, and liver cells respond less effectively to insulin. The pancreas may compensate by making more, but if it cannot keep up, blood sugar rises. Over time, this can lead to prediabetes or type 2 diabetes. Family history and other health factors influence risk, so diabetes should never be treated as a personal failure. NIDDK explanation of insulin resistance.
Strength training helps your muscles use glucose more effectively. When muscles contract, they can take up glucose through pathways that do not depend on insulin. With regular training, the body can also become more sensitive to insulin. Resistance exercise helps build or preserve muscle and improve strength, making it a useful part of diabetes care. Exercise benefits can occur even without weight loss; the scale does not capture every improvement happening in your body. American College of Sports Medicine exercise consensus.
Strength training can include weights, resistance bands, or exercises using your own body weight. A starting session might involve standing up from a chair, wall pushups, and band rows. A qualified coach can help choose suitable movements, teach technique, and increase the challenge gradually. The goal is a manageable program that develops strength over time.
Swimming offers another way to stay active, particularly when exercise on land feels uncomfortable. Water supports your body, and many people with joint pain find exercising in the pool more tolerable. Swimming can also improve mood, making the experience rewarding beyond the workout itself. CDC guidance on swimming and health.
You do not have to begin by swimming continuous laps. Depending on your abilities and comfort, an instructor may start with supported movement, walking in shallow water, or short swimming intervals with rest. Learning basic water skills can make future exercise more accessible. The first goal may simply be feeling comfortable enough to return.
Combining aerobic activity with strength training makes sense for blood sugar management. In a randomized trial of adults with type 2 diabetes, a program combining aerobic and resistance exercise improved A1C compared with a group that did not exercise. A1C is a measure of average blood sugar over roughly three months. Swimming is one way to include aerobic activity, although that particular trial did not test swimming specifically. Combined exercise trial.
Some people with type 2 diabetes achieve remission. Exercise can be a powerful part of treatment, but it is not a guaranteed cure. Remission generally means an A1C below 6.5% for at least three months without glucose-lowering medication. It requires continued monitoring because blood sugar can rise again. Strength training and swimming can support a broader care plan, but neither activity alone guarantees this outcome. International consensus on diabetes remission.
Improved blood sugar control is still a worthwhile result when medication remains necessary. Type 1 diabetes is a different condition involving the loss of insulin-producing cells; exercise does not replace the insulin needed to manage it. CDC explanation of diabetes types.
Stress deserves attention, too. Stress hormones can make blood sugar less predictable, and feeling overwhelmed can make daily diabetes care harder. Enjoyable movement, adequate rest, and support from other people can help with stress management. If swimming becomes a welcome break in your week, that is another reason to keep it in your routine. CDC guidance on diabetes and mental health.
For many adults, a routine can gradually build toward:
- At least 150 minutes of moderate aerobic activity each week, using swimming, walking, or other activities you enjoy.
- Strength training at least twice a week, adapted to your abilities.
- Short, manageable sessions at first, increasing activity as your confidence and capacity grow.
These are general adult goals. Children, people with disabilities, and people with diabetes complications may need different recommendations or adaptations. Your healthcare team can help match activity to your health, medications, and starting point. Pair activity with an eating plan, adequate sleep, prescribed treatment, and weight management when appropriate. NIDDK activity guidance.
If you use insulin or a medication that can cause low blood sugar, plan ahead with your diabetes care team. Exercise can lower glucose during activity and afterward, so ask when to check it and how to respond to changes. NIDDK exercise precautions. At the pool, keep your glucose monitor and fast-acting glucose nearby, and let your instructor or lifeguard know about your diabetes. Medication changes should follow your clinician’s guidance.
