I'm a thirty-year old woman who wants to lose weight for about 14 kg. However,I also want to get pregnant.. Is it safe to use all types of exercises in air climber?

So you want to lose 30 lbs; I suggest you try before you get pregnant. As to the stair climber, why this? Walking for one hour a day and eating sensibily will encourage your metabolism to shed the pounds at a safe rate.

Moderate exercise is good while pregnant; aerobics is good.
