—most definitely you should for a few reasons.
When you workout whether it's going for a quick run, bike ride, exercise class, lifting weights or playing a game your putting the muscles under stress by contracting them.
This causes the muscles to fill with blood, produce lactic acid (by product of muscle contraction), micro tears, inflammation and causes increased tension on the body as a whole. Now I'm sure all of us want a fit & tight body but having excessive tightness is not good because it restricts the bodies ability to move easily and freely.
So by stretching your body and the muscles you just worked has many benefits such as;
• Faster recovery
• Reduced muscle soreness
• Helps slow down heart rate
• Restores normal muscle length/tension
• Maintains normal muscle function
• Helps maintain good posture
• Makes you feel good
Now if your uncertain how to stretch properly or you just need that extra help being committed to stretching you could sign up for a yoga class or get a massage. But with me being a flexibility coach/therapist, I'd recommend getting stretched by myself or another certified flexibility therapist. Just saying:)
