Interval Training
Posted by Andre on 07 Jun 2006 | Tagged as: Exercise
This week I’ve included some interval training into my cardio (on the x-trainer) workout. Here is what you do…
1. 30 seconds run like Dr Death is chasing you
2. 30 seconds rest (slow right down)
3. Repeat for a long as you can
I tested the method out with my little 20 minutes and 300 calories benchmark test just to see how fast you do burn calories.
I’m told if you can do this method for 10 minutes then you’re pretty fit. I tried 20 minutes
I selected Level-9 on the x-trainer (which still enables me to get up to a fast sprint) and went for it.
My 30 seconds sprints got the speed rating up to 20+ (not sure if that represents is 20KM/h). I dropped the speed to around 7 for the 30 second rests.
After a few minutes the 30 second rest intervals really don’t seem all that sufficient. It was eventually taking about 20 seconds for my heart rate just to start to lower… leaving just 10 seconds for me to drop 15 heart beats per minute. Phew!
Anyway…
Managed to burn 305 calories in 20 minutes. It was hard going, that is for sure, but I can certainly see how someone can become *extremely* fit doing this method of training as part of their weekly workout schedule.
Fitness is really the measure of how quickly you can lower your heart rate. In other words, if you get you heart rate up to say 170bpm — fitness is how quickly you can get it back down say 122 (differs with age group, of course).
If it takes you 2 minutes to go from 170bpm to 122bpm, then that is a measure of your fitness level.
Now try a few weeks later and see if you can get from 170bpm to 122bpm is less time, like 1 minute. That means you’re getting fitter. LOL!
