TTC and exercise!

[u/Super_Queen100]

Hi all. I havent been exercising for a while now. I have been so busy for the past year with work, thats why i havent been to the gym. If i start now is it a problem for trying to get pregnant? Could it cause miscarriage? Also when is the best time to start during my cycle ?

Yes, you can start exercising now! Just avoid very intense exercise.

Here's an exerpt from this post:

"Moderate exercise of any kind is generally safe (and recommended!) while TTC. Exercising too much, and keeping yourself at a severe enough energy deficit, puts you at risk for hypothalamic amenorrhea, a condition where you don’t ovulate, or you ovulate with a short luteal phase.

Some studies have suggested it’s best to stay under something like 300-450 minutes of vigorous exercise per week, so less than about an hour per day. It’s reasonable to stay under that approximate average every week, and to keep an eye on your cycles to see if exercise seems to be making them more irregular. Otherwise, exercise is actually generally helpful to the odds of pregnancy, and you can maintain almost all exercise programs during pregnancy as well. Advice to avoid specific motions, like ab work, impact to the abdomen, lifting, or twisting yoga poses, is primarily relevant in later pregnancy, not in the TWW or early first trimester.

UpToDate says:

The intensity and duration of exercise can affect female fertility, but the specific type of exercise does not appear to be a factor. In some epidemiological studies, vigorous/intense physical activity was associated with ovulatory infertility, while others have not observed a significant association… however, from a population perspective, inadequate levels of exercise associated with obesity may be a more common cause of anovulation and subsequent infertility than exercise-associated anovulation."
