You can exercise anywhere even without equipment.I remember ages ago reading about a prisoner who called himself Charles Bronsen after his hero. He was superfit despite spending most of his time in solitary.He said you can do lots of exercises in a tiny cell e.g.running on the spot,resistance training against walls and floor exercises etc.
I'm not suggesting he should be your role model but he does illustrate how we can always find ways of getting fit providing we have basic good health and the will to do it.
Best of luck with your programme and I'm sure just looking after your little baby will keep you active!
