Day 1 was a fun challenge for me. I was able to have good form with the crab position. I did not experience any pain, but I could not keep my form once I tried to walk it because my hips kept dropping and my heart rate sped up very quickly!
I did the crab position again on day 2 and I was able to walk a little more than the day before but that night I started experiencing a bursitis type of pain in my left shoulder when I was in bed lying on my left side.
Does this mean I should temporarily discontinue doing the crab position? Can I still continue with the fundamentals?
