Yes, if symptoms live above the neck - Mayo Clinic says mild to moderate exercise is usually fine with a common cold and no fever, and may even ease congestion briefly.
Below the neck means stop: chest congestion, hacking cough, stomach symptoms, fever, fatigue, widespread aches. NYU Langone adds: sweating out a fever is a myth, training febrile worsens dehydration risk, and you should wait a few days after the fever breaks. Half intensity, honest self-check, and skip the gym - colds are contagious.

What to do
Common questions
Can I exercise with a cold?
Yes, if the symptoms live above the neck - that is the standard rule and Mayo Clinic backs it: mild to moderate exercise is usually fine with a common cold and no fever, and it may even open your nasal passages temporarily. The line is anatomical: runny nose, congestion, sneezing, minor sore throat - reduce intensity and go. Below the neck means stop: chest congestion, hacking cough, upset stomach, and definitely fever, fatigue, or widespread muscle aches - those are systemic illness, and training through them stresses a body already fighting. Two additions from NYU Langone's sports-medicine guidance: sweating out a fever is a myth - exercise raises heart rate and temperature and worsens dehydration risk when you are febrile - and after a fever breaks, wait at least a few days before resuming. Scale it: half your usual intensity and duration, indoors, and honest self-checks - if the warm-up feels wrong, the session was a walk. One more courtesy: a cold is contagious, so the gym version of this answer is a home workout.
