Vo2max - breathing - belly pain

[Hosant]

I actually experienced something similar and reported it here:

So, today I did Braid +6 as part of Build Medium part and this is was by a significant margin the most uncomfortable workout I have done, perhaps ever. However, the discomfort wasn’t on my leg muscles or my heart were I normally expect it to be and I can power through, but my belly due to strong breading. It was really painful for that lower part of my body. So much that I considered stopping the workout, a first in a very long time. Any tips to avoid that in the future? Thanks!

What I ended doing was just to tough through the intervals and overtime the belly pain lessened and it wasn’t an issue after a few weeks.
