Exercise affect ovulation?

So I know when to chart ovulation and cycles, but I don't know if they are affected by anything. I know AF is late or skipped with a new intense exercise regimen or a new diet, but I didn't know what effect it had on actual ovulation. Let's be realistic, I am not planning on
​Starting to run marathons or anything, but we have been working in the yard carrying large stones and heavy wheelbarrows etc. on month 2 of TTC and wondering if this is affecting chances?
