According to docs orders, just listen to your body. If u feel tired slow down, drink more water and enjoy yourself. Walking is good at the gym. M trainer told me last week that when im on the treadmill to increase the incline at a lower pace. Everyone will be helpful at the gym. Just ask them.

after the pregnancy i had to dial it down a little. My doc recommended keeping Zumba and adding swimming. I do zumba 3x a week and another cardio on the fourth day

Before I conceived I was working out 4 days a week. I was on a pretty vigorous plan: personal training 1x a week, hiit training 1x a week, zumba 2x a week
