Perhaps the people who made that tier list thought being of body-builder-esque strength (likely without the body type, muscle mass, and all the ramifications that has) was more combat applicable than running at 60mph. 

Looking at it though it does seem a bit odd, perhaps people were having trouble with the metric system. I can lift about fifty five pounds in one arm and I'm in no way built or super-human. Lifting 300kg would be more impressive. 

The tier system always was a bit derpy though.
