Do you know any good resources for stretching?

• Infographics

• Websites

• Youtube videos or channels

• Etc.

Dos and don’ts are also useful.

I have no issues or problems but I am in late middle age and my level of inflexibility disturbs me a little. So I’m going to stretch twice a day so that as the months go on - things will improve.

I already started using my rowing machine a lot so I want to continue to be on a roll.
