Been feeling a little bit wheezy the last couple of days, hence no HIIT - until today. Didn't want to miss another day so I tried a burst on the rower followed by a burn on the treadmill. Except after really struggling on the rower - 6 reps 30/30s - I decided to HIIT the bike instead of the treadmill and subsequently struggled there too - 5 reps 30/30s. I don't feel unwell. I just almost feel like coughing but without actually coughing. Tomorrow will be better.
