Garrett McNamara, who also goes by ‘GMAC,’ is an American professional big wave surfer, and extreme waterman, known for breaking the world record for largest wave ever surfed around the world. He has been a passionate surfer since his family moved from Pittsfield, Mass. to the beaches of Hawaii and he has never looked back. McNamara's professional career spans over two decades around the pacific and beyond.

Don’t let McNamara’s laid-back, surfer persona fool you: as an professional athlete in his mid-forties, an age at which most are thinking of stepping to the sideline, he's ramping it up a notch. His recent world record wave ride in Portugal was on a wave ranging from 90-100 feet in height, and for him it was just another day at work.

That day that was six-plus years in the making. McNamara was tipped off to the wave by an email sent from a small village on the coast of Portugal. A local that wanted to know if the wave, a geographic phenomenon off the coast of Portugal called the North Canyon, was worth riding.

Living with the constant quest of riding the “barrel” or “tube” of the wave, McNamara's adventures include surfing in Alaska on a wave caused by the falling ice of a glacier into the frozen arctic waters. McNamara admits it was "a little crazy, but worth the risk, because the falling ice creates perfect waves."

He credits his survival to planning and fitness along, with his ability to hold his breath. McNamara is currently taking classes so he can surpass his personal best of 4.5 minutes under water.

“You have to survive the beating the wave hands out,” said McNamara, “and sometimes the bottom is a bit rough, like a coral reef, so you really just take a series of breaths whenever you can.”

Over the past 10 years, McNamara has been on a mission to catch the biggest, best waves on the planet, and he has succeeded. He is arguably the most committed ocean explorer in the world. You can put him in any situation in the water and GMAC is not only ready to go, but go hard!

At 17 years old, McNamara entered and placed in the prestigious Hawaiian Triple Crown Series. Along with his brother Liam, McNamara began to attract the attention of major sponsors and signed deals with a number of prominent brands in Japan. The brothers spent the next 10 years on the competition circuit, traveling and becoming fluent in Japanese. It was the realization of a dream come true for both brothers.

McNamara continued to push the limits of pro surfing, and soon he started to get towed into waves on Personal Water Craft or Jet Skis, which enable surfers to chase down and catch giant waves that were thought to be impossible, beyond the reach of surfers paddling with their bare hands.

Predictably, McNamara couldn't leave well enough alone. He is still on a mission to explore the world’s oceans for the best and biggest waves Mother Nature has to offer.

“The past is history and the future is a mystery” says Mr. Fitness, Tony Horton. “Feel good now, work out now and make it a habit.”

Horton, the founder of fitness regimen P90X, takes no excuses for delaying fitness and preaches both nutrition and activity. One of his main themes is “clean up the diet and get off the sugar, the fats, salts and chemicals, processed foods that come from boxes and bags.” If you go to www.beachbody.com and check out his orginal program, titled Power 90,you can see Horton's recipe for weight loss and nutrition.

His new program, 10 Minute Trainer,sounds too good to be true, but as he explains in the second part of the Radio BDC interview, it's just to get people started in forming good habits – so 10 minutes turns into 20 minutes, and it grows from there.

After the success of his first two books, Bring It and Crush It, he is launching his third, out this summer. There seems no end in sight for his fitness empire expansion, which includes a video game, food line, clothing line and sunglasses.

Tony Horton is a motivator and he has built his success on making getting fit both fun and effective. His approach is sometimes corny, and often over-the-top, but the bottom line is: his programs work.

So if you're looking to break free of the winter and looking towards a spring and summer of fun in the sun and feeling better about yourself, start any one of his programs and stick with it.

Just check out his web page www.tonyhortonsworld.com. You’ll be glad you did.

Tony Horton has risen to heights rarely found by fitness trainers. This kid from Rhode Island, who describes himself as a “high school weakling,” has created a fitness empire that has produced the top fitness program of all time.

In almost any circle, if you mention Tony Horton, P90X, or the" fitness guy on TV," people will know the program, or, more than likely, have done it themselves.

The P90X regimen appeals to people for many reasons. Tony explains, “Its fun, fast-moving, and you don’t need fancy equipment or a gym. But more importantly, it works.”

The results do speak for themselves. After doing the P90X program, I have to admit that as hard as it was, the hour work outs went by quickly. The mix of Horton’s simple slapstick humor and encouragement keeps your mind off of the task at hand, and before you know it, you have done some crazy move on one leg with your arms touching the ground and reaching for the sky.

Add to that the Beach Body website, where there are resources like coaches, an online directory of exercises, fitness products and a community of friends that are helping you stay true to eating right, working out and having fun. And this mass access to fitness has taken away the mystery of staying fit and looking good.

Tony says he works out 22 days a month and that most people can achieve 18-22 days a month and should not be discouraged by the amount of time of each work out. He preaches routine and has a gospel of remaining young and beating back the hands of time through a mix of yoga, nutrition, balance and core strength.

His products range from the “10 minute work out” to the new P90X2.

The fact that amazes me is I have known Horton from his humble beginnings when he first started coming to my ski camps out west and in South America. And to watch him build his fitness following has been inspiring. I have witnessed people driving over nine hours just to shake his hand and thank him for changing and transforming their lives. His programs have not only been inspirational, but his commitment to helping people change their paradigm about themselves and the world around them is the underlining power of his success.

We caught up with Tony Horton just as he returned from a heli skiing trip in Canada for a special Edging the Xreme Radio BDC two-part series on fitness.
