I know exactly what you are going through. I stopped cycling while the three girls started to grow up. They are 9-15.
now it's time to get back on the bike. You have to find the time. Even if it's 1 hour on the trainer it's better than nothing. Even with the cold weather here I had 275 miles on the trainer and at spin class.
My biggest complaint is that I can't lean far another forward because my legs hit my belly.
But I know the more I work out the better off I will be.
I set goals for the month and find ways of getting what I need done.
