How to fight stiffness on a long flight
Walk it out. Stroll th e aisle every 20 to 30 minutes. It’ll keep blood flowing to your leg muscles and help prevent blood clots. If you find the space, add squats and quad stretches every hour.
Move your feet. While seated, periodically tap your toes for 30 to 60 seconds. And add in some calf raises: Lift your heels and squeeze your calf muscles, then lower and repeat 20 times.
Roll every joint. Drop your chin and slowly roll your head toward your right shoulder, hold, then roll it to the left. Roll your shoulders forward and backward, then do the same for your wrists and ankles.
Twist your spine. Cross your right leg over your left and place your left hand atop your knee and your right hand on the seatback. Inhale and rotate your torso, holding five to 10 seconds, then switch and repeat for the other side.
