Weight training lowers blood sugar right after exercise in sedentary young women, but walking or jogging at the same effort level does not, meaning the type of exercise matters more than just how hard you work.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether resistance training consistently produces greater acute glucose-lowering effects than aerobic exercise across diverse populations and protocols.
A systematic review and meta-analysis of all RCTs comparing acute blood glucose responses to resistance training versus aerobic exercise in sedentary adults, standardizing exercise duration, intensity (e.g., 75% 1RM vs. 60–70% HRmax), and glucose measurement timing (0–30 min post-exercise), including at least 20 studies with total n>800.
Whether resistance training produces a greater acute glucose-lowering effect than aerobic exercise when matched for caloric expenditure and session duration.
A crossover RCT with 40 healthy sedentary women aged 18–26, each completing three 30-minute sessions: resistance training (75–80% 1RM, 10 exercises, 3 sets), aerobic exercise (5–6 km/h treadmill), and a calorie-matched high-intensity interval session, with blood glucose measured pre-exercise and at 0, 15, and 30 min post-exercise in randomized order.
Whether women who prefer resistance training over aerobic exercise have lower average fasting glucose levels over time.
A prospective cohort study following 1,000 sedentary women aged 20–35 for 5 years, categorizing them by primary exercise preference (resistance vs. aerobic), and measuring fasting glucose annually while controlling for diet, sleep, and total physical activity.
Whether women with consistently elevated postprandial glucose are less likely to engage in resistance training compared to those with normal glucose responses.
A case-control study comparing 150 women with abnormal postprandial glucose (≥140 mg/dL at 2h) to 150 matched controls, assessing lifetime resistance training frequency and intensity via validated questionnaires and activity monitors.
Whether current resistance training habits correlate more strongly with lower fasting glucose than aerobic training habits in sedentary women.
A cross-sectional survey of 600 sedentary women aged 18–30 measuring weekly resistance and aerobic training volume via accelerometers and self-report, alongside fasting glucose and HbA1c, adjusting for BMI and dietary intake.
