2)Siłownie na które idą młode zdrowe osoby, dzięki którym rośnie odporność są zamykane.
Pobiegać czy pojeździć na rowerze można i bez wchodzenia do siłowni. Na odporność najlepsze są rekreacyjne ćwiczenia, a nie wyczynowe (typu bicie rekordów w maratonach czy wyciskaniu na klatę) prowadzące do DOMS (delayed onset muscle soreness) - https://pl.wikipedia.org/wiki/Op%C3%B3%C5%BAniona_bolesno%C5%9B%C4%87_mi%C4%99%C5%9Bni . DOMS obciąża układ odpornościowy.
Wyciskanie ciężarów powoduje podobną reakcję układu odpornościowego co intensywny trening wytrzymałościowy: https://pubmed.ncbi.nlm.nih.gov/7558530/
The data demonstrate that leg squat exercise to muscular failure results in a very similar immune response to that associated with intense endurance exercise, despite a lower mean oxygen consumption and only a moderate hormonal response.

It doesn’t. It taxes your immune system, weakens it.
Repairing the damage done by lifting weights is a process in which the immune system plays a significant role. In normal conditions, your immune system can only take so much. That’s why when you hit a draining session, especially if you tend to accentuate eccentric portions of movements, you can get sick. Flu or cold symptoms aren’t uncommon.
Even if you only do it recreationally it is already enough to weaken the immune system by redirecting some of its resources.
From a perspective of 17 years of experience in lifting, 7 recreational and 10 competitive, I was never once fully healthy. There’s always some runny nose, slight cough now and again and other symptoms typical for flu or cold. Of course, I only got sick 3 or 4 times during that period but it feels more like stretching the same thing over a very long time.
When I talk to my counterparts, their experience is mostly similar.
From the bloodwork done many times over the years, My WBC count is always elevated a little. Neutrophils or eosinophils also come elevated most of the time, indicators of different kinds of infections. And this is the only thing that comes out of whack. Hormones, electrolytes, etc, always come back normal. Again, I heard of similar situation among other people that are involved in weight lifting sports. It kind of seems a normal thing, to keep progressing you need to keep your body stimulated - in a constant process of repair - and that drains your resources.
In conclusion. It doesn’t, it’s stimulating for the body and keeps you in one piece, but there’s no benefit in lifting weights when it comes to the immune system function.
Can Too Much Exercise Make You Sick? https://www.active.com/fitness/articles/can-too-much-exercise-make-you-sick
But can too much exercise really make you ill? A study conducted at the Los Angeles Marathon reveals that this may be the case. Results show that:
One out of seven runners who participated in the event got sick after it was over.
Runners training more than 60 miles a week during the two months before the race, doubled their odds for sickness compared to those training less than 20 miles a week.
But regular moderate training also appears to provide protection against colds. Eighty percent of fitness enthusiasts, for instance, reported in a recent survey that they have fewer colds than their inactive peers.
So what's a coach to think?
Too Much Exercise Suppresses Immune Function
Although moderate exercise may help protect athletes from sickness, training for too long at too high an intensity appears to make athletes more susceptible to illness.
Laboratory research shows that athletes exercising at a high intensity for 90 minutes or more experience a steep drop in immune function that can last up to 24 hours. The drop in immune function appears to be caused by the elevation of stress hormones released during and following heavy exertion. This is what exercise immunologists believe allows viruses already in the body to spread and gain a foothold.
