Cardio Interval Training

Interval training is not for the timid, follow the guidelines below for best results with your workout.

Interval Training Guidelines
I know cardio interval training has become all the rage these days, but you should step into this area of cardio with some note of caution.

Interval training is very intense, and places great stress and demands on the respritory system and taxes muscles and the nervous system severely.

If you've been sitting on the couch eating pizza and drinking beer for the past 3 years, please do youself a favor and get some general conditioning under you belt before you even think of attempting interval training!

Cardio Interval Training Workout

use a stop watch or wrist watch to time your intervals

For this interval training workout, I am assuming you will be running, but the same principals apply if you are on a treadmill, elliptical machine or exercise bike etc.

(1) Warm up at a comfortable intensity for 5 minutes with a brisk walk, calesthenics or a slow jog. When the warmup period is over, proceed with the intervals.

(2) Next, run at maximum effort for 15 to 30 seconds, followed by a 2 minute recovery period of walking slowly.

Perform between 6 and 8 of intervals, and finish with a nice slow walk for about 10 minutes to cool down.

On you next workout (space out a few days) you can add one or two intervals, or you can increase the duration of your sprints to 30 to 40 seconds.

I know this interval training workout looks easy on paper, but trust me on this will leave you gasping for air if you're going all out on each interval.
