Caravan Training is a HIIT!


In the past several months I Think I Can Fitness has been quietly and diligently developing a new workout program called Caravan: Group Personal Training ©. It is an experiment that questions some of the basic foundations of the fitness industry.

  • Do you need to workout at a gym to get results or can you do it at home?
  • Can the latest piece of workout equipment be a high-speed internet connection instead of a $1000 machine?
  • Can in-person access to a qualified personal trainer cost less than the typical $75-$100 per workout?
  • Do you really need to workout for an hour at a time or can you make progress with less?

I can’t address all of these questions in this blog post but if you’d like to learn more about the program as a whole checkout our sign up page.   What I want to focus on most is the last question:  Is a long-duration workout really necessary for general fitness and/or weight loss?

The alternative to long-form workouts are HIIT Training Workouts:

The general principle behind this type of training is that short periods of very intense exercise can have equal or greater effects on general fitness level than long periods of steady-state cardio.   It has also been shown that HIIT training increases the capacity for fat oxidation.

There are a lot of  runners who write for and read this blog.  We are not, by any means, advocating that you stop running!  Running is unquestionably a great way to improve your fitness level, meet great people, get outside, and maintain a healthy heart and lungs.  But I would encourage every runner, in fact, everyone (who has been cleared by their physician) to try some form of high intensity training.

There is a technical definition of HIIT training workouts that involve certain measures of physiology. I don’t think it is necessary to get into the fine details unless you want to become an elite athlete.  For almost everyone short periods of  ‘sprint-like’ training will yield physiological benefits (see ‘The Benefits of HIIT” below).

Our new workout paradigm, Caravan, involves 10-minute long HIIT-inspired workouts. Conventional wisdom says that 10-minutes is too short a time period to do much good. Workouts should be at least 30 minutes and up to 2 hours in duration.  But I wonder how much of this comes from health clubs and/or organized sports.

For instance, if you run a health club your clientele must travel to the health club, get signed in, change clothes, workout, then shower, change clothes again, sign out, pay for parking and then travel home.  There is a lot of transistion time here, even if you are walking from work.  So in this case it does seem silly to workout for anything less than 30-minutes so that your 60-minutes of traveling and preparation makes sense.

Likewise in organized sports there are a lot of people who all have to be scheduled to meet at the same place at the same time.  It doesn’t make sense to do this in less than hour long chunks.

But in the age of the internet a lot of things become possible that weren’t possible before. Many people now work from home saving a lot of time, money and wear on the environment.  Also, I personally have half-a-dozen friends who met long-term partners online through internet dating services.  So why not add exercise to the list of things that can be enhanced by the internet?

Efficiency of HIIT/Caravan Workouts

If all you have to do is turn on the computer and start working-out, with no one else’s schedule to coordinate, and very little transistion time, the 10-minute HIIT-style work suddenly becomes possible.

Is ten minutes of physical activity a day enough?

No.  We all need more than 10-minutes of physical activity a day.

But if 10-minutes is all you got for the day than I would argue that those first 10-minutes of working out provide a disproportionately large amount of the benefits of working-out.   Getting in at least that 10-minutes a day is vitally important.  It builds a habit.  It gives you an incredible mood and energy boost. (Don’t believe us? Give a workout a try, on us!).  It prevents the significant muscular atrophy that can happen in only a few days of not working out at all. And just doing those 10-minutes starts a snowball effect, where you are inspired to be more active the rest of the day.

The first 10 minutes is as valuable as the next 20.

Tip: The Center for Disease control advocates 150 minutes of cardio per week.  But they say that it doesn’t matter how or when this exercise occurs.   In fact, according to the CDC, 10-minute chunks are just fine, as long you are getting in the recommended total minutes per week.

Our hope is that Caravan is a way for people to get 10-minute workouts that improve posture, reduce the risk of injury, and provide exposure to the HIIT philosophy of training.

Tip:  Caravan can be adapted to meet all your exercise needs.  Consider your next business trip or the next time you find yourself at the in-laws for Christmas.   Simply do each workout 3x a day.  3 workouts x 5 weekdays equals 15 10-minute workouts for the full, CDC recommended, 150 minutes.

Our fondest hope for this experiment is that we can expose people to the benefits of HIIT, in a way that is safe, convenient and affordable.

 The Benefits of High Intensity Interval Training

HIIT Benefit: Improved Mood

Mood Improvement and Feeling of Rejuvenation

*Increased Energy

*Lightening of Mood
Not a lot of quantitative research in this area. But in our experience the world seems a lot brighter after a hiit workout. Conduct your own study. Try a workout.


HIIT Benefit: Fat Burning

*Alters Metabolism for 24-hours after the workout.
