Yes and yes.
For me, running and exercise is really important. It is for DH too, so we prioritise it, and fit it in where we can. I do some form of exercise every day.
So, for example, I run home from work, stopping at the gym on the way - just for 10 mins - to lift weights. I also have a kettle bell at home that I chuck about while DS is watching Cbeebies. In my previous job I worked too far away to run the whole distance, so would get the train halfway and run the rest.
I also fit in a half hour fast run on my lunch break, where I can, and run wherever possible - such as to nursery to pick up DS, or home from meetings etc.
As DH is fit too, weekends are active for us as a family. We might all go to the park and take it in turns to have a half hour run while the other watches the children. Or we'll bike ride as a family.
It's harder since DC2 was born and I'm more tired with night feeds, but it's about squeezing it in where you can. Tonight all I had was a 20-min window while DH was cooking tea, DS was in bed and DD was napping, so I did a fast run then.
Am currently still losing the baby weight, as DD is only 3 weeks old, but with DS I lost the weight in 7 weeks and then lost a further stone and a half.
It helps that DH prioritises exercise as much as I do, and understands that we both need to do something every day.
