GRID FOAM ROLLER
The Grid Foam Roller is a US patent, representative of myofascial release.
Not only is it characteristic shape, but it also has been clearly clearly specified when to use.
When you use PRE-GEN, start with foam rolling at the first of your warm-up to improve muscle movements.RE-GEN (after exercise) is effective for cooling down.
The grid foam roller also has a special shape and exquisite hardness, which can provide proper compression and stimulation to deep muscles.Unfortunately the same effect cannot be achieved with all urethane cylindrical products, products made to imitate the hardness and shape, and parallel import products that have not good preservation.
When using the grid foam roller, be sure to take moisture properly.
