When I went to the gym when I was in my 20s and 30 I could notice the difference after a cold and flu. I'm by no means a body builder but I got to a comfortable point of weights for me.
If I had a cold it would set me back a day or two sometimes not at all but I didn't go to the gym when sick. If I had the flu even with a flu shot it knocked me off my weight routine for months. The effects of having the flu was very noticeable on me it set me back six months. I can't imagine what covid would be like.
I exercise 1.5 hours a day 6 days a week for long time now..agree colds/flu would knock me down, though i don't get them that often. I had covid a few times already and did not see any difference from just regular colds, well except i lost taste and smell which was a travesty not being able to taste all that bland chicken going down the chute :D But I am not seeing any effects in my performance or new gains. I guess everyone's different
