I got sucked into Dave Tate’s Reflections Part 1 and Part 2.  Tate is a career powerlifter, sale and he was briefly involved in CrossFit.  There are some Tate videos about powerlifting and developing strength that are worth watching.
Tate, information pills like many career lifters, check is a no-nonsense guys.  After years of relentlessly moving heavy stuff, some truths must become apparent, and the Iron never lies.  I really enjoyed Tate’s thought on injuries in training.  Bottom line: if you are training to be fit or strong, injuries are avoidable.  Back off the weight, and recover.  But, if you looking to compete, and to maximize your genetic potential, you need to ride the razor’s edge of elite performance and injury.  You will need to push it.  I’m not writing this as any recommendation to “push it” and get hurt, but having experiences some injuries, I get it.
And according to Tate’s views on longevity, many of us are in the 3-7 year period.  Which makes us mere pups.
