Q: Should I skip my workout if I have a cold?

A: It depends. "If your symptoms are mostly above the neck (runny or stuffy nose, sore throat, or sneezing), it's okay to exercise," says Michael Seril, a personal trainer in Whittier, California. "Just do a less intense workout than usual." For example, walk instead of run, shorten the length of your usual cardio routine, and decrease the sets or reps of your strength-training exercises. "If your body is aching, you're severely congested, coughing, or have a fever, skip your workout," Seril says. When you're feeling better, gradually build up to your old routine.
