Is it possible to become more flexible after the age of 40?

Can you tell me if it is possible to become more flexible after the age of 40? I notice that as I age my body is becoming more and more immobile, perhaps this is due to my sedentary job and sedentary lifestyle.

Yes, of course, you can become more flexible at any age, age is almost irrelevant, the only important thing is that the earlier you start practicing stretching, the more chances you have to tone your body faster and make it more flexible and agile. And you can start practicing right now in the stretching studio or in Coach Flexderek's online courses at https://flexderek.com/en/stretchingonline/.
