Everything he said is true...
I will take that with me and keep an eye out at our Crossfit gym and keep those half ass reps on check. Thank you.
I will take what I learned and prevent this from happening.

Crossfit is still the best
Since our police force, SWAT, fire men, & many other athletes use Crossfit as a way to get back in shape or to stay at high performance level.

At the end of the day Crossfit is meant to enhance your lifestyle and make everything easier for you.
