I am 16 weeks with twins, and have still been struggling with low energy. I just finished college classes for the year, so I am off for the summer (other than taking a few classes online). I was wondering if it is more important for me to get in a bit of walking everyday (my doctor said I should keep it at just walking) or if it is more important for me to just rest and not worry about being active. Before I was pregnant I was pretty active, I would go to the gym and jog 3-4 days a week and I lifted weights. During the first trimester I was pretty sick so I didn't do much, so it is hard to get back into a routine. Any suggestions? Or others who are dealing with this problem?
