As an active individual dedicated to a healthy lifestyle, you know the importance of incorporating both cardiovascular exercise and resistance training into your routine. While the benefits of hitting the weights to build strength and muscle are well-documented, have you considered how your blood glucose levels may be impacted during these sessions?

Resistance training can pose some unique challenges when it comes to blood sugar management, especially for those living with diabetes. The intense nature of lifting weights can cause blood glucose to spike, while the subsequent muscle contractions may then lead to a rapid drop. Staying on top of these fluctuations is crucial to avoid potentially dangerous hypo- or hyperglycemic episodes.

So, what's the best way to monitor your blood glucose before, during and after resistance training? Let's dive in.

Checking Levels at Key Timepoints

- Before your workout: This establishes your baseline level and helps you determine if any adjustments to insulin or carbohydrate intake are needed.

- During your workout: Checking 30-60 minutes into your session can alert you to any significant spikes or drops so you can take appropriate action.

- After your workout: Testing 15-30 minutes post-session allows you to see the full impact of resistance exercise on your blood glucose.

Tracking these data points over time can help you identify patterns and better anticipate how your body responds to weight training. Some people find it helpful to keep a detailed log of their workouts, blood sugar readings and any treatment taken.

Leveraging Continuous Glucose Monitoring

For an even more comprehensive view of your glucose fluctuations, you may want to consider using a continuous glucose monitor (CGM). These small, wearable devices provide real-time readings that you can observe throughout your workout.

Many CGM systems now integrate with smartphones, allowing you to easily track trends and receive alerts if your levels start to climb or plummet. This can be incredibly valuable intel, especially if you tend to experience significant spikes or crashes during resistance training.

Making Proactive Adjustments

- Adjust insulin dosing: Work closely with your healthcare team to determine if you need to reduce your rapid-acting insulin before a strength training session. You may also need to slightly increase your basal insulin to counteract the prolonged glucose-lowering effects.

- Consume fast-acting carbs: Having a small, easily digestible carbohydrate snack (like glucose tablets or juice) 15-30 minutes prior to your workout can help prevent hypoglycemia.

- Stay hydrated: Drinking plenty of water during your resistance training can help minimize blood sugar spikes.

The goal is to find a personalized plan that allows you to reap all the benefits of resistance exercise without experiencing dramatic blood glucose fluctuations. It may take some trial and error, but staying diligent with monitoring and making timely adjustments can go a long way.

So, the next time you hit the gym for a strength training session, be sure to pack your blood glucose meter or CGM. Paying close attention to how your levels respond can unlock valuable insights to optimize your health and fitness journey.
