Kegel help strengthen the pelvic floor, which acts like a hammock when carrying a baby. Doing kegel also may help with preventing the "leak" we experience when pregnant and after and you sneeze or laugh.

ftm.... I don't even know how to do this tbh and I'm nervous to ask my Dr....

I think it helps the elasticity of that muscle also so that itll stretch easier and tear less? I think... Lol i also heard to massage almond oil to that area starting around 26 weeks to help it stretch also

it strengthens the muscles. just like lifting weights would for the rest of your body

It helps make them more "elastic" so they expand easier... You are practicing using your muscles. So say you started lifting a 5 lb ball with your right arm. At first it would be sore and harder to do, over time it gets easier and there is no pain.. So you're pretty much practicing the movements your vagina will make during labor.. and helps after birth too!!
