eli5 – If our cells only turn a certain amount of times before we die. Does causing micro damage from resistance training shorten our lifespan?

Question

I’m not even sure how to put into words my question but I’ll try.

From what I understand telomeres shorten during cell turnover which causes ageing. Therefore do activities that cause cellular damage like resistance training, tattoo or laser resurfacing etc shorten your lifespan or cause you to age?
