Actor Mark Wahlberg has officially joined Power Plate as an investor in parent company, Performance Health Systems and brand ambassador for the product. He will also consult on strategy, product and programming development.

Wahlberg has a long history of investing in fitness through his Mark Wahlberg Investment Group, having been an early stakeholder in F45.

He reports having been a Power Plate user for 15 years, saying vibration training plays an important role in his own training and wellness-focused lifestyle.

"The fact Power Plate has been relatively unknown for so long surprised me," said Wahlberg. "I've been a satisfied customer for over a decade, so I decided to get involved in spreading awareness about their game-changing products."

"It's not often you have the opportunity to align with an individual who can impact every facet of a business, from personal investment and business strategy, to increasing brand awareness and credibility, yet that's exactly what Mark brings to Power Plate," says said Lee Hillman, CEO of Performance Health Systems. "He's a rare individual whose voice resonates with consumers on a truly global level.

"Over the years, Power Plate and vibration training has been validated by medical, academic and exercise science and yet it remains a bit of a mystery to too many people. We believe Mark can play an invaluable role in changing that, and we couldn't be more thrilled to have him on board," he said.

"Mark is so much more than a celebrity investor. He brings a deep understanding of fitness methodology, nutrition and business strategy," said Hillman. "His involvement in our business carries with it an enormous array of possibilities, and we intend to explore them to the fullest."

For Wahlberg, Power Plate is the latest addition to an investment portfolio that includes other fitness-oriented brands and ventures in addition to F45, including Performance-Inspired nutritional products and Municipal sport utility gear.

The actor is well-known for undertaking physical transformations to enable him to play specific roles, including piling on 56lbs of muscle to take him from a low of 165lbs to 221lbs.

His most extreme role to date was as a bodybuilder in the film Pain & Gain.

Wahlberg has 16.3m followers on Instagram and regularly posts details of his workout regime, which includes going to bed at 7.30pm, rising at 2.30am, doing a 90 minute workout starting at 3.40am and with a second workout in the evening.
