HIIT (High Intensity Interval Training)

In the past we have been bombarded with information from books, magazines, television shows and fitness experts about the right way to burn fat; 65% of your maximum heart rate for more than 30 minutes, three or more times a week. It’s true that this WILL burn fat. However, this classical view of training is not the only (or even the most effective) way to burn fat through exercise. Enter High Intensity Interval Training (HIIT). Read the rest of this entry »

Treadmill HIIT – No Thanks

It’s only been around a week since I posted up a poll (you can see it on the right side of the site) about where people prefer to do their HIIT, and unfortunately it’s clear already that running on the treadmill the most popular way to train – I say unfortunately because it’s not really the ideal environment to HIIT.

In order to HIIT effectively it is important that your high intensity intervals are explosive, short, bursts of speed and power. On a track or elliptical trainer this poses no problems, you can simply run faster or pedal harder because you are in control of all variables, on a treadmill however you are limited by the rate of the treadmills acceleration and deceleration, aswell as it’s max speed. So often I hear from people saying that have been doing HIIT on a treadmill alternating between 8mph and 2.5mph. THIS IS NOT HIIT. Not only is 8mph too slow for a high intensity interval, but the treadmill cannot go straight from 2.5mph to 8mph and back quickly (and why would they? That would be dangerous).

The HIIT routines I recommend!

As we’ve established in previous articles, there are various ways to HIIT effectively. In this article I’m going to give a few sample routines for different methods.

Sprinting

The following routine is not conventional in terms of HIIT, the intervals aren’t consistent and it’s a little short – but it’s a good one to mix up your normal routine and keep you body guessing. This routine should kick your ass, if it doesn’t (athletes) then extend it. NOTE: not good for beginners or anyone very overweight. Read the rest of this entry »


Get a Heart Rate Monitor – thank me later

If you’ve read some of the other articles here at HIIT Source, you will know that the best way to monitor yourself during training is by keeping an eye on your heart rate and adjusting your intensity to suit the needs of your exercise program. How do you do that quickly and effectively? A heart rate monitor of course.

For cardiovascular exercise (and especially HIIT) the best type of heart rate monitor is a 2 component design; chest strap and wrist display. The chest strap is wrapped around your chest and takes a reading directly from the signals of your heart, then wirelessly transmits the reading to a wrist display (a watch).

Monitoring your HIIT intervals

In this article I will be outlining the pros and cons of various ways to monitor your HIIT intervals.

Time

This is by far the most popular way to monitor your intervals. Traditionally you will find HIIT routines around the internet which will tell you how many seconds your high intensity interval should be, and how many your rest should be.

This isn’t always a bad thing, but there isn’t just one cookie cutter HIIT routine that will suit everyone, especially beginners. Read the rest of this entry »


HIIT swimming

Warning: High Intensity Interval Training is VERY hard! If you are not a strong swimmer, I would not recommend this type of workout for you. Exhaustion could lead to drowning. Please make sure you are properly supervised while doing HIIT in the pool, by pool staff or a friend.

This is just a quick article I’ve been meaning to write because for all you people above the equator, warm weather is coming in the next few months and it’s easy to sit inside your air-conditioned living room and use the “too hot!” excuse.

Luckily, there is a way to get your High Intensity Interval Training in while still keeping cool – HIIT swimming. Read the rest of this entry »
