Hi I have 3 kids the youngest is only 13 weeks like what has been already said if your head is in the right place you will fly through it, am n week 4 having lost 19lb so far and I've started 30day shred yesterday so far so good. Take it easy the first week and after that un will be amazed at he energy levels I just to be in bed for 10 these nights am still at 12/1 o clock and up again 8/9 in morning as well as some times during the night. Good luck in your journey the first week drags but am finding these weeks fly.
