Crystal's Bodyweight Workout

Today Crystal starts a new workout. She will be doing the 4-Week Bodyweight Program for Beginners. This workout consists of two strength workouts that are alternated every other day and an interval workout that she performs after each strength workout. Since the holidays and my travel schedule will have her visiting her parents house a lot, we thought a bodyweight based workout would allow her to keep working out even when she can't get to the gym. Her schedule will be like the following:

Day 1 Workout A followed by Interval Training
Day 2 30 minutes of activity
Day 3 Workout B followed by Interval Training
Day 4 30 minutes of activity
Day 5 Workout A followed by Interval Training
Day 6 and 7 30 minutes of activity

The next week is the similar but with workout B done twice. Each strength workout targets your entire body and doesn't last more than 20 minutes. The whole workout including warm-ups is complete in 45 minutes which is important. We don't particularly like to work-out, it's not a social activity for us. What we need are effective workouts that get the job done quickly and this program should accomplish that with ease.
