January was one of the worst month in a while.

I've got sick in the first week of the month and the sickness prolonged through the month. I only had higher temperature sometimes before bed, felt tired and weak most of the time. I could not cancel work so I worked on paracetamols. What is killing me most is my workout progress. I am advanced pilates practitioner and am planning to do hyrox race this year. I've got 5 workouts in in whole month instead of 6 weekly. Now I am scared I will get sick again if I overdo it again, because I regularly get sick after weight training.
