When you construct your schedule, make sure to: Leave at least 48 hours between weight workouts of the same body parts. Your muscles need time to recover and repair themselves after a workout. Take 1 day each week to rest with no formal exercise. Warm up for 5 minutes before starting to exercise, either through a light jog, riding on a stationary bike, jumping rope, or doing slow jumping jacks.
The three components of your weekly schedule
2. Additional cardiovascular exercise: Optional, on non-strength-training days. Examples are cycling, running, swimming, walking, and using cardio machines. An interval workout is recommended for 1 day a week, and light cardiovascular exercise like walking is recommended for 2 of your 3 off days.
3. Abs exercises: Twice a week. I recommend doing them before your strength training or interval workouts.

Your Weekly Workout Schedule
Here, you're going to do circuit training to
 optimize your muscle-building potential. That is, you'll perform one 
set of an exercise and then move immediately to the next exercise, with 
just 30 seconds of rest. Follow the order of the exercises here; that will allow you to work different body parts from set to set. (Click here  for a complete set of exercise descriptions and instructional photos.)
By alternating between body parts, you'll keep your
 body in constant work mode and be able to perform the movements 
back-to-back without rest. Here's why circuit training works so well: 
You'll save time because you'll cut the amount of rest you need when you
 alternate muscle groups. More important, you'll keep your heart rate 
elevated throughout the workout, so you'll burn even more fat while 
you're exercising -- whether it's in the gym or in your own living room.
In the first 2 weeks of the program, do the circuit
 twice. Move from exercise to exercise with no more than 30 seconds of 
rest in between. When you complete one circuit, rest for 1 to 2 minutes,
 then complete the second circuit. After the first 2 weeks, when you've 
become comfortable doing two complete circuits during a workout, 
increase your workload to three circuits per workout. In every exercise,
 use a weight that you can handle comfortably for the number of 
repetitions noted. When that becomes too easy, increase the weight on 
each set by 10 percent or less. Here's a sample schedule of how you 
might arrange your workouts.
