My workout routine while being pregnant isn’t as intense as when I am not preggers. I do have to really listen to my body and make sure I am helping and not hurting myself and baby. I tend to do a little cardio and then a circuit based mostly with lightweights (pregnant women are encouraged to use weights no more than 25lbs). Then I usually will go into abs (yes you can do abs while you’re pregnant) and then stretch. This gets me sweating a bit and gets my heart rate up without overdoing it. Recently, before I had known I was pregnant, I was doing hard cardio classes such as spinning and then intense circuit classes that literally give you no time to breath. I know pregnant women continue to do these types of workouts and they’re fine but for me it just wasn’t happening. Although, I will take a more resistance based cycle class once in a while.
