- You can't increase a muscle's length by stretching it. You can only increase your neural stretch tolerance.
- To increase flexibility, adhere to the specificity principle. Increasing passive ROM is best achieved by 30 seconds of static stretching in a position as close to the desired position as possible. Increasing active ROM is best achieved by performing the desired movement against a resistance over your maximal ROM.
- Keep warm-ups short and to the point. Prepare your body for the specific task at hand.
- If you want to change your posture, you need to become aware of it and correct it until holding your new posture becomes automatic.
However, mobility does have its place.
If after two months of frequent stretching you still can't perform a movement, you likely have poor technique, a muscle imbalance, or soft-tissue restrictions.
In which case, fair enough. But to me, unless you need it, it really doesn't fit in to a normal workout routine
If you want to increase your ROM in a movement, like squats, the most effective way is simply to do the exercise. Ironically, it's often the most ardent haters of isolation exercises that prescribe isolation stretches for this purpose.
However, contrary to stretching, resistance training can also increase muscle length. The key is to strengthen the muscle eccentrically in its lengthened position.
If someone has short hamstrings, doing good mornings or Romanian deadlifts is more effective than any possible amount of stretching.
I don't think anyone here is saying do stretching before training.
