The tiger tail is an implement used to perform a form of self myo-fascial release.
Using the tiger tail on the forearms is a great way to warm up and cool down for your workout, especially if you plan to perform upper body exercises that require the forearms to be more mobile.
When you perform SMR on your forearms, or any muscle group for that matter, you alleviate some of the tension that is built up during the day and your workouts.
