Yoga Foam Roller
The foam rollers are made from EVA foam that is compressed, high-density, made for the perfect workout at home or in a studio. The foam roller is lightweight and easy to carry around, making it portable and for use whenever and wherever you want. Usually, the foam roller is used for stability exercises, but freedivers use them for stretching the chest area to coop with the pressures of depth, or back and lung stretching.
The foam rollers come in the diameters 10 and 15cm with a length of 30 and 90cm.
