Greetings Dear @ashkhan,
Thank you for the revue and feedback of my first course on this Steemit Learning Challenge module s21w1.
(Always apply the heating pad before doing these exercises and stop exercising if you feel unbearable pain because some exercise triggers pain) your suggestion has benefited me quite a lot, I didn't know it.So I'll definitely follow up when doing the next exercise.Also I'm not a professional physiotherapist I'm a patient.Still I tried to answer according to your question. I apologize to you for my efforts.Hope you look at my mistakes with forgiveness.and I'll definitely try to clear them up next course and Warm greetings for you.
