If there's anyone who can fight the toughest battle against cancer, it's the successful fitness professional and industry leader, Peter Twist.

Peter Twist (Twister) has been a longtime friend of ACE, so like many others in the fitness industry, we were moved when our friend, Todd Durkin, posted that Twister was diagnosed with Stage IV nasopharyngeal cancer (head/neck) that had spread throughout his lymph system. Since he was diagnosed last year, he has been battling the cancer, receiving "chemotherapy and radiation at the highest level one can receive."

Twister said this left a severe burning sensation in his mouth, face and neck.

Even through this challenging year, Twister has maintained his intensity, positivity and passion for life.

“I believe survival is in part determined by a will to live, a will to love, and a willpower to do the hard things well every minute during challenge, pain, and suffering. Become very passionate about LIFE and engage in activities in a way that grows WILL and WILLPOWER,” Twister said to Durkin.

And his business, Twist Sport Conditioning, website reads, "Life is short. Live Everyday. Today I will give everything I have, what I keep inside I will lose forever."

This positive energy to achieve the best and help others do the same — no matter the circumstances — is not surprising to our ACE fitness experts who have been inspired by Twister when working together.
