Foam rollers are inexpensive, yet highly effective tools that relieve soft tissue pain and muscle pain. Athletes often use them to break up scar tissue and painful adhesions that develop after years of workouts. Using foam rollers is similar to getting a massage from a bodywork professional, but you can use the rollers on your own at home or in a gym.
There are five general types of foam rollers. A Grid roller is firm on the inside, yet has a soft foam outer layer. This type of roller is best for serious massage work for injuries. Molded foam rollers form after tiny beads compress to form a solid log. These rollers are known for their durability. EVA foam rollers are easy to carry and keep their shape. They also last a long time and provide a lot of pressure. A high density foam roller is very firm and best suited to serious athletes, because it really works out the muscles intensely. Finally, the low-density foam roller is inexpensive, but it doesn't work out the muscles as much as the other types.
