Strength Training Below the Surface: Exxentric Aboard Canadian Submarines

We love seeing where people take their training with Exxentric. This time, it’s beneath the ocean.
Royal Canadian Navy submariners are using our kBox flywheel equipment to train at sea—and we’re delighted to see their experience featured in Pacific Navy News.
A submarine is an extraordinary place to find an Exxentric setup. It is also a place where the reasons for choosing flywheel training become very clear. Space is tight, noise matters, and every piece of equipment has to earn its place aboard.
From astronaut fitness to training at sea
The project brings together two fascinating training environments. Having worked with the Canadian Space Agency on astronaut fitness, the Human Performance Research and Development team at Canadian Forces Morale and Welfare Services applied that experience to the challenges facing submarine crews.
Flywheel training offered a way to fit a wide range of strength exercises into the space available, without storing and moving heavy weights.
The feedback that made our day
The article describes how the crew adapted to the equipment, including its versatility and ease of use in a confined space. Two comments from submariners sum up their experience:
“the first proper workout I have done on a submarine.”
“It took the place of our rowing machine almost instantly, and with countless more workout options.”
It’s encouraging to see the kBox being put to use in such a demanding setting—and to hear directly from the people training with it.
Thank you to the Canadian team for sharing the story—and to the crews putting the equipment to work below the surface.
