Take time to stretch. The change you are seeking with this step is to stretch a minimum of 20 minutes, three times per week.
If not with exercise, take a brisk five- minute walk first. Do each stretch 2-4 times, for a duration of 10-30 seconds. Stretch major muscle groups first. Do NOT bounce in stretching. Breathe in deep, steady breaths, stretching should be felt, but not painfully so.
Good times to stretch are early on the morning, and after sitting for a long period. If you need guidance, there are all sorts of good stretching routines available online.
