Whether as a warm-up before sport or for active regeneration afterwards: the foam roller lets you do both for your thighs. The only difference lies in whether you roll quickly or slowly. Also, if you've spent the entire day sitting down, the foam roller can be really beneficial for your thighs. The adductors might feel painful while rolling with the foam roller, but it's a "pleasure-pain" situation here, as afterwards your thighs are guaranteed to feel more relaxed. So get started now and add the foam roller to your routine for your thighs.
