A few weeks ago, Linda, 70, told me with a sigh, “I walk every single day like my doctor said. My watch shows I’m getting my steps in. But my blood sugar numbers are still bouncing around more than I’d like.”

Linda was doing exactly what most people are told to do for diabetes — steady cardio. Walking is wonderful for the heart, mood, and circulation. But it turns out there’s a missing piece that many people never hear about.

Your muscles are one of the body’s best tools for managing blood sugar.

When you use your muscles — especially with strength training — they act like a giant sponge. They pull glucose out of the bloodstream to refuel themselves, and they do this even when insulin isn’t working perfectly. This effect can last for hours after a session, helping keep blood sugar steadier.

Cardio (like walking) burns some sugar while you’re moving, but it doesn’t create the same long-lasting “sponge effect” that strength work does. Studies show that adding strength training 2–3 times a week can improve insulin sensitivity significantly more than cardio alone for many people with type 2 diabetes.

The best part? You don’t need heavy weights or long workouts. Short, safe sessions with proper form can make a real difference.

Timing also matters. Doing a little strength work after a meal can help blunt the blood sugar spike that often follows eating.

You’ve been giving your body this powerful metabolic tool every time you train with us — building muscle that quietly works for your blood sugar even on the days you’re not exercising.

This week, try this simple awareness check after one of your movement sessions (or even after a meal):

Notice how you feel 30–60 minutes later. Are you less sluggish than usual? Does your energy feel steadier? If you check your blood sugar, see if the numbers look a little calmer than they have in the past.

Let your body be the teacher — it will show you when the muscle “sponge” is doing its job.
