Is it possible to always improve? Or is it
unrealistic to assume we can always get better?
CrossFit takes the approach "attack your
weakness." What ever it is that you are not
good at or hate to do, is precisely the thing
you should work on. For example if you hate
Thrusters, make it your daily chore to practice
and get better at them. Take your weakness
and turn it into your strength.
