How ' s the sizing ? I ' m torn between a small and a medium . 5 ' 8 158 lbs athletic build <| sep |> Thanks for your answer . I ' m still not sure what you mean about pelvic tilt though , because that is not something I control conciously . Or are you saying to move in a certain way that replicates having pelvic tilt ? I will try the cold shower thing , but I ' ve also been recommended to take hot baths ! Also how do you gauge whether you are holding excess tension in your body ? <| sep |> Yeah , us and Bama are more than defenses with a pulse . Were some of the best in the nation and they still looked alright against us aside from the turnovers we forced and the redzone stops . <| sep |> I wish . It ' s just the only good part of it .
