Wow.
You obviously know nothing about me.
Lets start with the facts.
1) I am WAY older than 48
2) I have been powerlifting since I was 20
3) I have 2 masters degrees. One in Nutritional Biochemistry with an emphasis in the transfer of nutrients between the blood/brain barrier, and one in Exercise Physiology.
4) Until 2 years ago I held M2 records in the squat and deadlift
5) I have consulted for 2 NFL strength programs specifically for lineman
6) I have never had any injury due to my workouts or competition
7) I have trained with Rippetoe, Simmons, Bergman, and had the opportunity to get a day with Ed Coan.
All that is just off the top of my head....
You read a book and took a class. Yeee haw.
Don't get into a dick measuring contest with me. I do not know everything, but you have a long way to go to be able to sit at my table and get sarcastic, condescending and patronizing, with me.
I would be happy to discuss why a deep squat is perfectly OK, but I suggest you buy Starting Strength by Rippetoe and read that first. Until then, please let me quote him.
"Anyone who says that full squats are "bad for the knees" has, with that statement, demonstrated conclusively that they are not entitled to an opinion about the matter. People who know nothing about a topic, especially a very technical one that requires specific training, knowledge, and experience, are not due an opinion about that topic and are better served by being quiet when it is asked about or discussed. For example, when brain surgery, or string theory, or the NFL draft, or women's dress sizes, or white wine is being discussed, I remain quiet, odd though that may seem. But seldom is this the case when orthopedic surgeons, athletic trainers, physical therapists, or nurses are asked about full squats. "
In the meantime, I would be happy to pass along to all the people I mentioned above how you believe they are wrong, and you one doc and one book are right.
