I'm in my 5th month of pregnancy and have gained around 14 pounds so far, not bad.
So I'm trying to gain only 9 more by the time I'm done which is hard work to stay that low.
I swim 800 meters every other night and play raquetball on other nights or go for walks. The swimming is the best. My leg feels healed and with swimming it never gets aggravated. One thing I CANNOT due is pick up my nephew or son too much as carrying that extra 30-40 pounds really messes with my lower back and my left leg injury.
My current pregnant PR for swimming 800 meters, or 1/2 mile is 23:07.
Wish me luck.
