That's ok to disgree. Whatever works for you or anyone else, and don't disagree for the most part about working out. I have some do's and dont's for myself. Everyone is different, have different treatments, reactions, underlying health issues, and mentioning infections because they can be serious, turn for the worse quickly, with a compromised immune system like cancer, and chemo can lower them further, and reason they stop treaments sometimes due to a low WBC, so it was worthy to mention about excessive exercise, to my knowledge, and being in public places in case anyone is interested. I think I mentioned gardening too, which has baceria in the soil, cats like to frequent, and their feces can spread illnesses to humans. At least wear gloves, wash hands afterwards, some will say wear a mask, and definitely take precautions in a public pool or gym.

As far as exercising heavy can lower your immune system I still believe so, have read about it many times, and happened to me, friends of mine, who were heavy runners. Maybe our ideas of a heavy workouts are different? I'm talking 6, 7 days of heavy exercising, running, biking, or swimming, and serious weight lifting. 3 Days does not sound excessive, except if doing for several hours each time.

Good luck tomorrow.
