My experience is a bit different to what you are asking.

With my first pregnancy I was still doing weight lifting and cardio training, I was at the gym four days a week and yogo one night a week. I was lifting weights (under the eye of a PT) until the Thursday before I delivered on the following Monday and the night I went into labour I had just finished a yoga session when I went into labour I trained "down" as such with my weights and cardio, wore a HR monitor to ensure my HR didn't get too high the further I got into my pregnancy. I would have classed myself as being pretty fit, quite a bit of muscle and defined abs .

My labour was very quick, from waters breaking to first ctx was 45 minutes we got to the hosptial another 45 minutes later ctx had gone form 5m to 2 1/2-3min appart within that 45 min and I was 7-8cm on for my first assessment not long after arrival and DD was her less than 40min later, natrual delivery but I had two tears and then an episiotomy was performed. DD was 7 weeks early.

This pregnancy I am not allowed to do any exercise due to complications, my general activities are very limited, no lifting, no long walks, no yoga... nothing So I will be interested to see what happens this time....

The difference is that I was already fit and training before getting pregnant, generally it is not advisable to suddenly start a full fitness regieme when getting pregnant, you can certainly take up more exercise, but say going into starting weights or full on training isn't recommended. But the things you are doing sound good and I am sure it will be beneficial in some ways, but as to the effect it will have on your delivery I can't answer as I was training before hand and trained down in pregnancy.

Goodluck and hopefully it makes a difference for you, I ams ure that being a bit fitter will help your recovery xxoo
