how to reduce fatigue during workout
By slowing down when needed
Hello and welcome to Ask A Doctor service.
I have reviewed your query and here is my advice.
Fatigue can be reduced by first stretching the muscles and starting slowly. Relaxing or slowing down in between also helps.
Can also get blood tested for basic tests like CBC, LFT, KFT, Thyroid, electrolytes, lipid profile. This will rule out common causes of fatigue like anemia, hypothyroidism, liver problems, etc.
Hope this helps. Let me know if I can assist you further.
