Fantastic. Thank you. Cheers from California.

Fantastic explanation and very easy to understand. Thank you.

[@PedroGaio]

cheers mate, not even living in the UK anymore but my sister recommended your videos and they´re great

[@lexie_tiano]

great video. Thanks for the explanations. It was very clear

Tyson fury is that you?!

Thanks Michael bisping

This doesn't quite make sense. The "muscle spindle" is a stretch sensor. The "Golgi tendon organ" is a tension sensor. He says that when you activate both simultaneously, the reflex of both contradict and so the reflex of both are ignored. But, that explanation doesn't quite make sense. Because when you stretch without PNF, the muscle spindle reflex automatically contracts the muscle to prevent it from stretching more which automatically applies tension to the Golgi tendon organ which should result in this same PNF confusion. So, how exactly does it work? I believe what's really happening is that by attempting to contract the muscle you're slightly increasing the Golgi tendon organ tension while slightly relieving the muscle spindle stretch. This results in a decrease of the muscle spindle stretch reflex together with an increase in the Golgi tendon organ tension reflex causing the muscle to relax a bit more which allows you to stretch a little extra.

love it...

Excellent video! Thank you for the information.

[@gailying333]

You are the best teacher

[@americanistafurioso]

so would this be hold relax, or contract relax?

[@ashleyfrench609]

How long do the effects of this type of stretching last for?

[@badruddinhasansaky5881]

Would u please explain pnf strengthening techniques?

[@jamesmorris857]

Hi Hafez, as far as my knowledge goes (and it isn't very much) it is the same as the PNF stretching technique explained in this video as the 10 second isometric contraction is maximal and allows for the development of strength when repeated regularly. So a gymnast, for example, would 3 sets of hamstring PNF stretches on each leg in one session so they would have also done 3 x 10 second maximal contractions on each hamstring so this technique will allow for the development of flexibility and strength.

If I'm training a client and performing stiff leg d-bell deadlifts to stretch the glutes and hamstrings with weight resistance, should I do a PNF stretch with that muscle group before or after the exercise?

[@abdullahasif4275]

during autogenic inhibition, which muscle (quadriceps or hamstrings) relaxes in order for the performer to have an increased range of motion?

[@VivekSingh-pg3zq]

The muscle that was been stretched. In this case, the Hamstrings

[@josephchou394]

Nice and clear explanation!
