We know our stuff at Matrix, but sometimes, we just don't have the time to answer your questions to an in depth level. So we have launched #askmitch. You can ask questions on twitter, facebook, google or here on the blog. Just use the hashtag and we'll pick a few questions to be answered. So if you aren't sure how to integrate fat burners into your diet, or you need to learn more about HIIT then you might want to get in touch.
