Regular exercise and training should not directly harm your chances of getting pregnant. In fact, maintaining an active lifestyle is important for overall health. However, it's important to be mindful of not overdoing it. If your energy expenditure significantly exceeds your calorie intake, it can lead to a condition called "amenorrhea," where you stop having menstruations due to lack of ovulation. As long as you maintain a healthy and balanced training routine that takes your personal limits into account, you should not worry about it affecting fertility. It is always a good idea to consult with a healthcare professional if you have any concerns about how your exercise routine may impact your fertility.
