Are High Protein Diets Safe?

Among the “controversial” nutrition practices often criticized in newspapers/magazines and other media articles are the high protein diets followed by bodybuilders, strength athletes, and CrossFit enthusiasts. Registered dieticians, the health professionals whose job largely involves the formulation of diet plans for sick people, are often quoted in these articles giving warnings about the purported dangers of “high protein diets.”

Effective Treatment for CrossFit Injuries

“No current system of exercise generates more debate and contention among healthcare professionals (and exercise enthusiasts) than CrossFit. Some wholeheartedly embrace it while others completely disregard it. Either way, a very real problem arises when CrossFit participants sustain injuries, particularly when those injuries require professional attention.”

Stop Doing Exercises That Hurt You!

In our facility, corrective exercise and strengthening exercise is an important part of our treatment of patients… We weigh benefits against risks. And that should certainly be a consideration when selecting exercises for your personal exercise program.

“POLICE”: New Management Guidelines For Ankle Sprains

Ankle sprains may not seem like such a big deal, but in the United States, alone, an estimated 28,000 ankle injuries occur every day. Most people assume that these injuries are destined to resolve with rest, alone, and minimal self management. However, this is certainly not the case for everyone.

What is Achilles Tendinitis?

Achilles tendinitis is an inflammatory condition that involves the ‘Achilles tendon,’ the tendon that anchors the calf muscles on the back of your leg to your heel bone. This tendon is involved in walking, running, and jumping.

For our many friends in the bodybuilding community, we feel compelled to share with you this open letter from Arnold Schwarzenegger to his best friend, Franco Columbu:


You’ve heard me say that I don’t like when people call me a self-made man.

You’ve even heard me say that you’re part of the reason I could never accept that label.

But I wanted you to know why.

From the minute we met in Munich, you were my partner in crime. We pushed each other, we competed with each other, and we laughed at every moment along the way.

When I finally got to America, I was alone. I’d left my family, my country, my whole life behind. So when I asked Joe Weider to bring you to train with me, it was because I knew I wasn’t the same without my best friend. I could thrive without money, without my parents, but I couldn’t thrive without you.

I am devastated today. But I am also so, so grateful for the 54 years of friendship and joy we shared. The pumps, the chess games, the construction work, the meals, the pranks, the life lessons - we did it all together. We grew and we learned and we loved. My life was more fun, more colorful, and more complete because of you.

I will always miss you. But I’ll also know that a part of you lives on in me, in Debbie, in Maria, and in the millions of people you inspired every day you lived. And I will be there for Maria and Debbie, so you can rest now with no worries.

I love you Franco. I will always remember the joy you brought to my life, the advices you gave me, and the twinkle in your eye that never disappeared. You were my best friend.

Love always,
