Challenging Normal

Because of my week I am starting my week 3 training a day early. This morning's walk/jog was challenging but not torture. I went 3.5 miles in 45 minutes. This week the training has me doing a 5 minutes warm up walk, then a minute and a half run, followed by a minute and a half walk, then a 3 minute run, then a 3 minute walked, repeat, and then a 5 minute walk. I continued on for another for 45 minutes total. I ran for a minute and then walked for 2 minutes. I seems real monotonous at times but I have to stick with the plan. Rest days are important and my body might appreciate two in a row but that will not happen for a couple of weeks. I am really enjoying this training and not focusing so much on my weight loss but on fitness.
