Gotta start soon

I keep looking out at my two 2 yr olds and have that urge to get out there and get going on them with their ground work. It seems like I never have enough time and when I do have the time the weather won't allow it. Do I set aside a few hours each evening to at least go out and halter and brush and just work on some basics of moving from pressure and allowing me to touch ever part of their body. Both are so easy going and laid back but do need lots of work with leaving the others and being on their own. So what better way to incoporate weight loss and training by taking them for walks at night.

I am hoping to have enough time between coming home from work and doing homeowork and housework to take each one for at least a 1/2 mile walk every afternoon.
I only have 3 more weeks of work left and then am off for the summer and will have more time to devote to these two and my other 5 and get everyone back into tip top riding shape.
