Perhaps it’s me. I a bit confused about the question.
Are you referring to dynamic stretching or a warmup? Generally, one warms up and then stretches.
There are a host of stretches one can perform–myofascial release, static stretches, proprioceptive neuromuscular facilitation, active isolated stretches and dynamic and ballistic stretches.
It is important that you take the level of conditioning of your client into account to determine the type of stretch you will perform.
Hope this helps.
