I would be little nervous about the dojo with all the sweat flying around during kata and I assume

no sparring there. I take reasonable precautions and I turn my head away if others are going by me if I am running or exercising. I have limited my workouts to running and about 5 sets of pushups and exercise bands in my house. A little boring but I am no longer driving to gym which saves about 45 minutes a day on top of workout time with weights.
