Hi Everyone,
Are any of you doing interval training?
Interval training is a proven method of increasing aerobic and anaerobic fitness, and increasing it fast. It helps improve performance in endurance (aerobic) and sprinting (anaerobic) events such as road races (or just a weekend jog), and sports like tennis and basketball where endurance but also sprinting are part of it.
The idea to interval training is to set up work to active rest ratios (work:active rest), and as you get more fit you increase the intensity, decrease the recovery time, and/or increase the work interval. Here's an example for beginners.
If you currently run for 30 minutes at 6.0 mph, jog for 5 minutes to warm up, then increase the speed to 6.5 mph and run for 1 minute, then jog again for 3 minutes at 6.0 mph, then run again at 6.5 mph for 1 minute, and then continue like this for the remainder of the workout. You can do this on a bike, x-c ski, rowing, or whatever you do for cardio
Here it is in stages with a 1:3 work:active recovery ratio
Stage 1: 5 minutes warm up
Stage 2: 3 minutes at normal pace
Stage 3: work interval: 1 minute at higher intensity (for running it could be faster and/or uphill; for biking it could be more resistance and/or faster cadence)
Stage 4: recovery interval: 3 minutes at normal pace
Stage 5: work interval: 1 minute at higher intensity...
...and so on like this for the rest of your workout. Over time you will be able to increase the intensity and the recovery intervals.
You can also get more specific and use heart rate. Your heart rate is an excellent indication of how hard you are working. For example, if your heart rate is at 70% of your predicted max when you jog at 6.0 mph, then start at that speed and then either increase the speed or elevation, and increase it so that your heart rate increases to 85% or even 90% for 1 minute to start, then back to recovery at your jogging speed at a heart rate of 70%.
So, are any of you doing interval training?
