GET FIT IN 12 WEEKS

BACKGROUND INFORMATION

Here's what I've done to personally go from 19% body fat to 13%
in less than 12 weeks:

First a reminder! The 80/20 Rule: 80% of your fat loss will come from diet and 20% will come from cardio.

With that said, here's how I used a killer combination of cardio
workouts to slim up. My tool of choice was an upright, stationary bike in my home office but you can do this workout using any piece of equipment you want.  I chose not to do my early morning cardio workouts at the gym.

Warm-up/cool-down:  Before the beginning and end of each workout, spend 5 minutes in PRE 2 (see below) getting your blood flowing.  This means no hard breathing.  A cool down is important even more on the weeks you do high intensity interval training to pay back the oxygen debt you will have created.

The Rate of Perceived Exertion (RPE):  The most common measurement tool for assessing perceived exertion is a ratings scale named after its developer, Swedish psychologist Gunnar Borg.  The table below is modified for simplicity and answers the question "How you feel at the time you are asked." Here's what the numbers mean:

RPE 1-2 Very easy; you can talk with no effort.
RPE 3 Easy; you can talk with almost no effort.
RPE 4 Moderately easy; talking requires a little effort.
RPE 5 Moderate; talking requires some effort.
RPE 6 Moderately hard; talking requires quite a bit of effort.
RPE 7 Difficult; talking requires a lot of effort.
RPE 8 Very difficult; talking requires maximum effort.
RPE 9-10 Peak effort; no-talking zone

12 WEEKS TO A LEANER BODY

How it works:  Each week, you'll do two different cardio workouts, varying the intensity in slightly different ways and duration. By working close to your RPE 4-6 levels or 65% of your target heart rate (the point at which fat is used as energy), you burn fat. By working in your RPE 7+ levels of 75% and more of your target heart rate, you'll burn a combination of fat and glycogen for energy.  Your stamina will improve more during these workouts.

Interval Style Training:  On weeks 2,4,6 and 8,10 and 12, you'll perform your cardio interval style.  Alternate one minute RPE 7+ high intensity sprints with 2 minutes of recuperative stretches. 

12 Week Workout schedule:

Weeks 1,3,5 Perform four times per week

Exercise: Treadmill walk, exercise bike, stairstep    
Duration: 45 minutes
Intensity: PRE 5-6; THR 65% of Max
         
Weeks 2,4,6 Perform four times per week

Exercise: Treadmill walk, exercise bike, stairstep    
Duration: 20 minutes
Intensity: PRE 7-8; THR 75% of Max

Weeks 7,9,11 Perform five times per week

Exercise: Treadmill walk, exercise bike, stairstep    
Duration: 60 minutes
Intensity: PRE 5-6; THR 65% of Max
         
Weeks 8,10,12 Perform five times per week

Exercise: Treadmill walk, exercise bike, stairstep    
Duration: 30 minutes
Intensity: PRE 7-8; THR 75% of Max

Why it works:  High intensity interval training has been preached as the best way to do cardio.  It's short and intense, you burn as many calories and you are done in half the time. It's ideal for those short on time.  

On the other hand, moderate, longer sessions have worked for decades for those who are the leanest of lean. Competition bodybuilders. You'll find some of the most competitive bodybuilders doing 1 or 2 sessions of moderate cardio for 60 minutes per session. Sometimes twice a day!  Don't tell me longer sessions don't work.

The truth is, this type of program gives you the best of both worlds. Fast workouts on some weeks where you burn fat but you engage your upper cardiovascular system. And weeks where you just get into the fat burning zones and keep it there. Steady state cardio might be dead for some but the rest of us are doing just fine thanks.
