Day 22: 1st day -Thi Personal Trainer Lite

I downloaded Thi Personal Trainer Lite on my iphone. There are many workouts and options. Today I started on the Beginner Weight Loss #1. The workout incorporates cardio and weights. You do cardio for 5 minutes then weights for a few minutes then cardio for 2 mins then weights, etc etc. There are 27 steps to the whole workout. I went up to step 12 and got really tired. Yes, I am very out of shape. I will keep on working on it till I complete all 27 steps.
