The Standing Calf & Ankle Pump

Stand up and rise onto your toes, then lower back down, repeating at a steady pace. This activates your calf muscles, which act as a secondary pump pushing blood back up from your legs toward your heart, a job they stop doing almost entirely while you sit.

Lift one foot slightly off the ground and rotate your ankle in slow circles, then switch feet halfway through. This moves fluid through the ankle joint specifically, the area most likely to feel stiff or swollen after hours of sitting still.

Rock your weight from your heels to your toes and back, keeping both feet on the ground the whole time. This works the calf and shin muscles through a fuller range than standing still does, keeping blood moving through both sides of your lower leg.

Lift your knees in a light march, landing softly with each step. This is the fastest way to get real circulation back into legs that have been still for hours, using the same muscle-pump action as walking without needing to go anywhere.
