You are right to be wary. There is much bullshit. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic.

Your ideal body weight as an ectomorph at 6' 0" will be 214.378 lbs. There. Happy? And if you lose or gain a pound, I will have you killed. It is important to be ideal.

A weak man is not as happy as that same man would be if he were strong. This reality is offensive to some people who would like the intellectual or spiritual to take precedence. It is instructive to see what happens to these very people as their squat strength goes up.

Mediocre athletes that tried like hell to get good are the best coaches.

The full squat is a perfectly natural position for the leg to occupy. That's why there is a joint in the middle of it, and why humans have been occupying this position, both unloaded and loaded, for millions of years. Much longer, in fact, than quasi-intellect ual morons have been telling us that it's 'bad' for the knees.

Accumulating injuries are the price we pay for the thrill of not having sat around on our asses.

Only people willing to work to the point of discomfort on a regular basis using effective means to produce that discomfort will actually look like they have been other-than-comf ortable most of the time. You can thank the muscle magazines for these persistent misconceptions, along with the natural tendency of all normal humans to seek reasons to avoid hard physical exertion.
