Throat hurts after doing breathing exercises from lesson 2

I did the breathing exercises in the warm-up from lesson 2 and now my throat hurts... this is the second time this has happened. Anyone know why? I've never really understood breathing for singing but this throat pain has never happened to me before, so why now??

Hi, Jamal! You could be (1) taking in too much air and/or (2) using too much resistance. Try taking in less air and letting it flow more freely (not holding it back quite as much) and let us know if that helps!

Thank you for the reply Camille! 

Happy to help, Jamal!
