I do water aerobics 3 times a week. The other days I try to get walking/swimming in. It's great on your body and really helped me with the swelling. :)
I do 5 days a week at the gym just started in January. I am overweight and wanted to get healthy then surprise i found out I'm pregnant and currently 7 weeks. My daily routine is 20 mins on treadmill, 20 on bike or elliptical, 60 crunches or situps, then I work out my thighs, Lower back and other areas. My doctor said to keep working out and drink tons of water so i don't cramp up. My trainer also said just use your body as your signal and you will be just fine :) But I would definitely consult a doctor because we are all different and they know best.
Oh, I also have a dumbell routine I go through to focus on arms, back, and shoulders
Check out "40 weeks of fitness: prenatal workout series with Lauren Huber Griffith" on youtube. It's a little more advanced but she also has various steps on each move so it's easy to work up to the full thing. I also "sectioned" it in to 4 separate workouts that I'm mixing and matching. On top of this continue the walking! I'm doing a minimum of 5kms on my walks 3 times a week and working up towards 10
Sunday- 2 mile hike up hill
Monday- 2 mile walk/jog
Tuesday - 100 squats 100 push ups on knees
Wednesday - 3 mile walk/jog
Thursday - abs
Friday 2 mile walk
Saturday- 100 squats 100 push ups
Im not into yoga or the gym. The weather is so nice right now. I alternate walking trails. I love walking by the river. Squats are becoming harder but I wanna keep my booty in shape.
