Cardio vs Weights: Which Lowers Blood Sugar Faster And Which Lasts Longer?

                                                                                                                                                            Best Exercise for Diabetes: When to Walk, Cardio vs Weights, and How to Lower Blood Sugar Spikes Dr. Kulmeet Kundlas explains how many diabetics exercise incorrectly and outlines science-based strategies to control blood sugar short term and long term. He emphasizes that “muscle is medicine,” noting muscle clears about 80% of carbohydrate load and that building 10% more muscle can reduce insulin resistance by 11%. He contrasts aerobic exercise (brisk walking, treadmill, swimming, jogging) which quickly lowers glucose by reducing insulin resistance, improving insulin sensitivity for 24 hours, using an insulin-independent pathway, and increasing blood flow, with resistance training that increases GLUT4 “doors” on muscle cells and keeps them active longer. He recommends at least 150 minutes/week of uncomfortable-paced cardio plus resistance training 2–3 times/week, walking 10 minutes after major meals to blunt spikes, timing walks immediately for non-diabetics, 15 minutes after meals for prediabetics, and 30 minutes after meals for diabetics, with late afternoon/early evening providing stronger effects.
