It's always a good idea to try to lose weight before trying to conceive.
If you can keep active and avoid comfort eating (definitely harder for me during the pandemic) you can definitely lose weight easier before trying to conceive.
The recommended 150 minutes a week of moderate exercise (or 75 minutes of more intense exercise) definitely helps. That's a couple of walks or online cardio / Zumba / HIIT classes a week.
Yoga helped me lose my weight a lot faster.
Yoga burns calories when done the right way and coupled with the right dietary changes.
If you are serious about losing weight and getting fit, you might want to implement a 60-minute power yoga and/or vinyasa flow practice at least five to six days per week.
This yoga weight loss program was easy to follow and worked for me before trying to conceive and I started to put on too much weight.
Each class is easy to follow, but is varied and enjoyable. Dynamic Sequencing means you'll always be challenged regardless of your current level.
If you want to follow my example, think about coupling your practice with a whole foods diet for optimal results.
Good luck!
