I noticed that when I had a cold during high school. Weight training class would clear my breathing for a little while. Then I think by next period, I felt crappy again.
But please, if you’re working out at a gym with a cold, look for those spray bottles of disinfectant and wash down the machine! I wait until my discharge is clear and I just have that annoying chronic cough and then I go. I caught a bad cold from my granddaughter and also fell and bruised my ribs on the same day and it kept me out of training for a month. I’m just now getting back in the swing.
Exercising when sick is more often than not a good idea. Doctors overprescribe bed rest because it’s the safest course in terms of legal liability, not because it seems best for the patient.
Good advice. Give everybody at the gyms your gross germs.
Fine, work out all you want, but don’t take your virus to a gym.
