Stretching Progress Resets?

Edit Post

Do any of you guys experience this phenomenon where the amount you can stretch resets after waking up from a good night's sleep? For example, when I wake up, I can't touch my toes from a pike stretch. Later in the day when I do several sets of stretching, I am then able to touch my toes again. I have been consistent with my stretching, so I'm not sure what I'm doing wrong. I just don't want to lengthen and have the resets become continually harder to do until they are just simply impossible to achieve after several cms of lengthening.

It's completely normal. I am not going to explain why but just know that it is completely normal

Okay, thanks for the reply. I thought I was going crazy.

Your body just needs to be warmed up first, like with all exercise.

Your muscles get stiff when you sleep. You should be very flexible after a hot shower for example, cause they get relaxed.
