Is Quicker Always Better?

I read an interesting article the other day about a new exercise bike called Car.ol, designed to get you fit in 40 seconds using Maximum Intensity Interval Training (MIIT), sometimes also know as Sprint Interval Training (SIT).

Great headline that 40 seconds is all you need…

BUT, beware of the shiny fad.

When you read on, the actual workout is 9 minutes long, during which you perform two 20 second sprints flat out.

The rest of the time you’re resting or warming up or cooling down.

OK – so the science is solid… ish…

The research paper Car.ol’s makers refer you to, found that Maximum Intensity Interval Training (MIIT) was indeed more effective than 30 minutes of cardio.

However, the misleading fact is – the control group did steady state cardio at 50 – 65% max heart rate.

SPOILER ALERT: Pretty much any interval training at intensity is going to get better results than that.

Claire & I are all in favour of promoting new time efficient ways to train that get results.

But two 20 second blocks is quite frankly not enough.

Let me back up to the SCIENCE of it for a second…

Working at high or maximum intensity for short bursts rapidly depletes glycogen in the body.

It boosts your metabolic rate, burns body fat and over time improves your insulin sensitivity (making you more efficient at processing sugar for energy).

Car.ol achieves that, but so will a decent 10 – 15 minute HIIT session and you get more variety, hit more muscles AND have more fun.

If Car.ol floats your boat, then knock yourself out.

But with the price for one session starting at £24 (and you need 3 a week), and a bike of your own costing from £2995, please be aware that you have far better (and cheaper), more effective alternatives.

As you know we don’t like fads.

And we don’t like people (cleverly) skewing science to make their product sound more sexy.

As always, we’re here to guide and support you.
