The 25-minute threshold: Why prolonged sitting silences your muscles and how to counteract it
A study of 84 adults using electromyography shorts tracked 7,684 sitting bouts and found thigh muscle activity reaches its lowest point after 25 continuous minutes of sitting.

Walking or vigorous activity before sitting helps maintain more muscle activity during subsequent sitting compared to standing still beforehand.
Fidgeting legs during prolonged sitting improved blood sugar control and insulin response in a separate trial of 20 adults with obesity.
