Really helpful post-exercise. I used to get tight calves but using this foam roller on my calves after exercise helps break down the lactic acid buildup causing the discomfort.
In my opinion the firmness is just right. It may seem a little too firm on first use but for my case that was because my muscles were tight. After using this for several weeks I no longer suffer from issues from tight calves and my legs feel a lot better.
