Full-time PT Mummy here. Used to be 90+ kg now maintaining 65 for the last 3 years.
Things are very different now, but back when I was losing my baby weight (all 30 kilos of it!) this is what I did.
1. Woke up 20mins early & went for a walk/run EVERYDAY. If DD woke, DH would care for her until I got home
2. I downloaded a Pilates DVD & did that during DDs sleep (mainly on the rainy days I couldn't run)
3. After she went to bed at night I did 100 reps of any 1 exercise I chose (squats, sit ups, dips, whatever)
I lost the first 20 kilos quickly. Last 10 was difficult.
I alternated between clean eatting & low carb diets, joined a gym & went to a high intensity cardio class 3 times a week. Dd went to crèche. It was a tiny dirty gym that was falling apart but membership was $6 a week (so I paid about $2 a class)
It was hard! Going through it alone! But we couldn't afford anymore at that time (I even felt bad about the $6 membership!!!)
Every 3 mins of skipping once a day will start getting you results. Some days when dd was in a rotten mood it was all I could do but it all adds up in the end. Hope that helps xxx
