If that is the case a little stretching throughout the day will go a long way. You can improve your body flexibility on as little as 5 minutes per day if you stretch consistently. Here are some options: early in the morning, at work, after sitting for long periods of time, as part of your workout warm-up, after standing for long periods of time, when you are stiff, during your workout cool down and even when watching television or listening to music.

Stretching Tips:
Stretching should involve a slow, relaxed, controlled, and pain-free movement
You should maintain a stretched position (static technique) for a minimum of 30 seconds.
Adults should stretch once daily 3 to 5 days per week to maintain flexibility.
