Sounds like you are doing great. How long have you been using the KM? It would be better NOT to use the abdominal muscles at all... position change may help. Try a reclining position where your abdominals are relaxed, some prefer a reclining chair as opposed to a bed. Also try moving a pillow to tilt your pelvic area up a little. Every woman is different so you have to adjust your position or spring settings to work for YOU. Let us know if this helps a bit. Keep on Kegeling!
There simply is no treatment or device as effective as the Kegelmaster. Along with the "Second Device" which we provide FREE, it is virtually failureproof.
