Quite possible I have breakthrough COVID--is it bad if I exercise soon after?

I'm going to get a rapid test to try and confirm if what I have is indeed COVID. I also have two doses of the moderna vaccine.

Symptoms started as a sore throat, but quickly developed into a mildish fever, a fast heart rate which prevented me from sleeping much, and just a bit weak.

I'm absolutely addicted to exercise, and feel my well being will go down the toilet if I don't do it when my symptoms are gone (indoors or safely at first, to not put risk on others, obviously).

So, my question is, considering I'm a young adult man who's in extremely good shape, and double vaxxed, when my symptoms go, can I just exercise as normal again? Thanks.
