Day 10 brings us Rachel Elizabeth Murray’s views on high intensity interval training. Just one look at Elizabeth’s chiseled body shows us that HIIT, in fact, does work. Elizabeth is a certified personal trainer, nutritionist, and fitness model, among other things, so she’s got all the pieces in place to create a healthy (and fab) body. Let’s check in with her now to see what she has to share (I am almost going to guess that Fudge Covered Ritz are not on her list of “good” foods—a sad day for me, but I will live).
High intensity training forces the body to move from the aerobic energy system to anaerobic. In a nutshell, when you train harder and faster, you need more energy, and more energy faster! (Read: more calories are needed and subsequently burned to generate energy when your workouts are more intense.)
The good news is, if the workout is intense enough, you don’t have to do it very long
The good news is, if the workout is intense enough, you don’t have to do it very long. Duration can be, and sometimes should be (depending on individual’s conditioning level, energy needs, type of training and extreme levels of intensity) shorter.
Real life examples:
- Plyometric jump exercises (with very little rest)
- Athletic speed drills
- Some types of MMA training (level changes quickly)
- TABATA training
- Some types of cross fit workouts
- Or really anything that challenges you to move as fast as possible for at least 20 seconds, repeatedly, with little rest between ‘sets’
How to modify:
What are ways for people to get started on this who can’t do as much in the beginning ( i.e. if they can’t jump)? What can they do to reach a higher intensity level?
You can do many HIT exercises from the floor, or without jumping. You can even do sprints without any impact on an elliptical trainer or stair master while keeping your feet on the pedals the whole time.
On machines, try this: go 30 seconds as fast as you can go at a medium resistance, followed by 60 seconds low intensity ‘recovery.’ Repeat for as many times as you can in 20-30 min.
For floor exercises: Try something simple like ‘mountain climbers’ without jumping, and just move as fast as you physically can with a work/rest ratio of 20 seconds on/10 seconds off. Repeat for 4 min. You just did a TABATA set of HIT. Pick three more exercises and do them the same way and you’ve got a full HIT workout in!
