As someone said we all have the same 24 hours in a day what you do with them is up to you. Take a block of time in your day and set it aside as your time to exercise. Use your lunch hour at work. use some of your early morning time. do it while you do the laundry. Make a new bed time ritual for you and son of an exercise tape or two. It doesn't matter when but commit the time to you because you are worth it. You can do it. And as Dr Atkins says in DANDR if you aren't exercising you aren't doing his plan.
Happy low carbing.
