I have 3 small children, one of whom is a clingy breastfed baby, and my DHs work hours can be erratic. I have no childcare.
I really need to get out and start exercising again for my own sanity if nothing else - I never ever have time away from the children. It's been about 6 years since I last exercised as well!
So - I can get out for a jog about 20-30 minutes maybe twice a week but it's not guaranteed, and the days will change.
Is it still worth it? Does it HAVE to be a minimum of 30minutes and HAVE to be 3x a week to be of any benefit?
Pre children I used to do circuits, step aerobics, running, swimming, sailing and cycling..
