what’s the meaning of stretching.

Would I be guessing correctly that you mean stretching your body as an exercise or as an activity? If so, it's to loosen up muscles and joints. As an example, yoga stretching is popular to help people be flexible.

It is the continuous form of the verb stretch.

A rare Mesquite sighting . . . i hope you are keeping well.

Stretching: It's just to stretch the body part or extend the body body part to make flexible and healthy while doing exercise.

Stretching is the pre-exercise routine, done in order to warm up your body so that you do not get any cramps in muscles.

There are different kinds of stretching. Artists who work with canvas often stretch ( literally pull and then staple) the canvas over a frame in order to keep the canvas taut for the application of paint.

The dictionary definition can cover other uses of the word than just the matter of stretching your body for flexibility.

Thanks Setanta. I am doing well. I had a bit of a rough patch in '13 with Non Hodgkin-Lymphoma, but that has been in remission for 15 months now. Considering the mileage , I am not complaining . I hope you are keeping well also.

Hey, Mesquite!

Congrats on your remission.

I'm in that same boat (Mantle-cell lymphoma, an uncommon form of N-HL) diagnosed 20 months ago. After several treatments and procedures, I've been declared in remission for about 9 months now. Congrats and 3 cheers for modern medical science, right? A little bit of will power needed, though

I'm glad to see you post too, mesquite.
