How posture affects the pelvic floor

The way you carry your body all day affects the pelvic floor muscles. 
Some tips: 
Standing:  Keep your knees unlocked, buttocks and abdomen relaxed. 
Sitting: Use proper support for the back.  An additional cushion under the thighs keeps pressure off the pelvic floor and buttocks. 
Lying:  Elevate the legs on a pillow or two. 

Preventing stress on the pelvic floor
Lifting correctly
As you get ready to lift: 
Bend your knees
Gently hold in your stomach muscles
Exhale or breathe out as you lift (Don’t hold your breath!) 

Moving out of a chair
Take your bottom with you! 
Scoot to the edge of the chair 
Tighten the muscles around your vagina
Suck in your lower belly muscles
Push off the chair using your leg and arm muscles as you breathe out
