Dehydration, inactivity and stress all stiffen your back, not just age. Staying hydrated and moving regularly through the day are simple habits that really help.

Yoga, tai chi, Feldenkrais and strength training all improve balance and lower your risk of falling, at any age. A little regular practice goes a long way.

Break up long sitting spells every 30 minutes with a short walk, a stretch, or a trip up the stairs. Small, regular movement protects your body more than you’d think.

A run leaves your muscles full of lactic acid. Stretching afterwards speeds up recovery and keeps your muscles flexible enough for their full range of motion.

Slouching loads your tailbone, a delicate structure not built to bear weight. Find the balance point on your sits-bones instead, and your lower back will thank you.
