The word ‘tough’ has many definitions depending on the person you ask; Mondays, exam period, parenthood, running a marathon, competing at the Olympics – the list can go on and on.

But we here at myBody+Soul have come to the conclusion that there is a single definition for the term ‘tough AF’: the assault bike.

Regardless of whether you claim to be the world’s fittest athlete, or your pain threshold is higher than everyone else’s, you haven’t experience real pain until you’ve hopped on this machine.

Okay, so what in the world is this assault bike?

In short, think of a normal bike you’d find in your gym or soul cycle class… now turn the resistance up to a million.

Basically, it’s a modern take on the very old traditional air resistance bike that’s being modified with bearings instead of bushings to provide a powerfully smooth (and bloody tiring) ride.

What’s more is that it won’t just get your legs working, according to Fitness Manager from Fitness First, Chris Reid.

“The best thing about the assault bike is that is works your entire body,” Reid tells myBody+Soul.

“Combining power from both the upper and lower body creates an extremely challenging workout, but it also rewards you with an unprecedented level of calories burned on a piece of cardio equipment.”

And when he says “unprecedented” he really means flippin’ unprecedented. Just one minute on the assault bike can burn up to 87 calories, which means if you times that by 60, you can burn a whopping 5,200 calories in an hour! WTF.

But before you go Googling where in the world they sell these killer machines, we firstly need to point out that a maximum of 30 seconds will literally leave you feeling very assaulted, so doing it for a solid hour is practically impossible for anyone (but we’d love to be proven wrong).

Secondly, you don’t need to fork out thousands of dollars purchasing one – Fitness First has implemented this nasty machine in their Conditioning class at The Zone.

After been thrown onto the assault bike in this class, you’ll then take your wobbly legs through a series of other circuit exercises – think kettlebells, TRX, box jumps, treadmill sprints, and one too many ab exercises – that will leave you hobbling out the gym (yes, tried-and-tested).

If you’re not up for serious pain, you can also choose from one of the three other Zones – Progressive, Functional, or High performance Strength – which are just as tough in their own way.

According to the Fitness First site, “these four distinct areas are designed to push your limits and leave no ground untouched.”

Yes, we have officially deemed this the only place that’ll be able to whip us into shape in time for summer.
