IT LOOKS like a bolster and is made of material similar to that used in a takeaway lunchbox. But do not look down on the foam roller's unassuming, cylindrical-shaped exterior.
It really is a core training, stretching and massage tool rolled in one - and is perhaps the hottest exercise equipment on any athlete's must-have list now.
As Victor Khoo, managing director of local healthcare services group Core Concepts, put it: 'There's been a sudden surge in people buying the rollers from us in the past few months - even though we've had them since 2004.'
Usually about a metre long and made of high-density foam, these rollers have been commonplace for years in sports medicine facilities for rehabilitation.
Of late, they have become popular home training tools for both recreational and serious athletes, such as national swimmers and Ironman triathletes.
Lightweight and versatile, the foam roller costs $65. It provides an unstable surface and a challenging platform to do core-strengthening exercises.
Advanced athletes may even do dumbbell or medicine-ball exercises standing or lying on the foam roller.
A strong core can help athletes across all sports, according to Core Concepts physiotherapist Ng Chye Tuan, 26.
Good stability in the trunk, he explained, minimises inefficient and unnecessary movement during activity. For example, energy-wasting, side-to-side body movements in cyclists and runners are limited with a strong core.
Here, Ng shows five exercises that athletes should do three times a week. Warm up with some dynamic stretches before starting, and ensure your spine is neutral throughout the exercises.
'I recommend any athlete who wants to see an improvement in their performance to do them,' he said.
So, join the foam party - and you could be on a roll, soon.
