“10 squats every 45 minutes beat a 30-minute walk for blood sugar control”

## The Evidence Ying Gao and colleagues at the University of the Sunshine Coast recruited 16 overweight men in a three-arm crossover design: uninterrupted sitting, 30-minute continuous brisk walking, and 10-body-weight squats every 45 minutes. The squat protocol produced a 14% greater reduction in post-prandial blood glucose compared to the walk, and a 28% reduction versus uninterrupted sitting (Gao et al., *Scandinavian Journal of Medicine & Science in Sports*, 2024). ## Why This Makes Sense Skeletal muscle — primarily the quadriceps, hamstrings, and glutes — accounts for about 80% of insulin-stimulated glucose uptake. Each squat contraction temporarily activates GLUT4 transporters via a non-insulin-dependent pathway (AMPK activation), essentially forcing glucose into muscle cells without waiting for insulin signalling. Repeating this 8–10 times per hour maintains a near-continuous glucose drain that a single aerobic bout cannot replicate once finished. ## Limitations The study was small (16 men), short-term (single day), and excluded women and people with diabetes. Whether these benefits compound over weeks or months with consistent application remains untested. The squat protocol also assumed no chair access — real-world compliance may differ.
