The best time to stretch is directly after your walk. Problem areas may be stretched prior to your walk, but only after you’ve warmed up. Don’t bounce when you stretch. Instead, ease into a stretch slowly and hold gently. Stretch to the point where you feel a gentle pull, but never to the point of pain. Hold each stretch for 30-40 seconds. If you have a problem with a particular area, stretch that area twice (hold for 30 to 40 seconds, release, then stretch again.)
