Simple Exercises That Can Repair Tendons, Isometrics vs. Eccentrics, and More — Dr. Keith Baar

Dr. Keith Baar is a Professor at the University of California, Davis in the Department of Physiology and Membrane Biology. During his Ph.D. studies, his research revealed that mechanical strain on muscle fibers activates the mammalian target of rapamycin (mTOR) signaling pathway, a crucial regulator of muscular hypertrophy. Subsequently, he studied the molecular dynamics of skeletal muscle adaptation to endurance training under the guidance of Dr. John Holloszy, a legend in the field of exercise physiology, considered the father of modern exercise biochemistry. Building on all of this experience, he conducted research into tendon health and the potential for engineering ligaments, which could have implications for treatment and recovery from injuries.

Gary Vaynerchuk is a serial entrepreneur and serves as the Chairman of VaynerX, the CEO of VaynerMedia, and the Creator & CEO of VeeFriends. Gary is considered one of the leading global minds on what's next in culture, business, and the internet.

Known as "GaryVee," he is described as one of the most forward thinkers in business. He acutely recognizes trends and patterns early to help others understand how shifts in consumer attention impact the realities of the business world today. Gary's approach sits at the intersection of business and pop culture. He keenly understands how to bring brand relevance to the forefront. He is a prolific angel investor with early investments in companies like Facebook, Twitter, Tumblr, Venmo, Snapchat, Coinbase, and Uber.

This year, Gary unveiled his seventh book, "Day Trading Attention" where he provides fresh insights into navigating the modern social media landscape. Gary's expertise guides readers on harnessing underpriced attention channels in the digital age. He emphasizes mastering storytelling in these arenas and highlights the "TikTokification of Social Media," where content relevance surpasses follower counts. Businesses can leverage this shift to enhance their brand and boost sales. "Day Trading Attention" equips readers with essential skills to succeed in today's dynamic digital world. Gary also announced his first children's picture book, based on his VeeFriends characters, titled "Meet Me in the Middle”. The picture book, which will prominently feature two VeeFriends characters, Eager Eagle and Patient Pig, delves into the emotional elements essential for nurturing children's empathy – a crucial skill for their future success.

Gary is an entrepreneur at heart – he builds businesses. Today, he helps Fortune 1000 brands leverage consumer attention through his full-service advertising agency, VaynerMedia, which has offices in New York, Los Angeles, Toronto, Mexico City, London, Amsterdam, Sydney, Singapore, Tokyo, Bangkok, and Kuala Lumpur.

He also owns a Major League Pickleball team called the 5s, is part owner of a Big3 basketball team, and is an investor in the revival of the SlamBall League.

Gary is also the founder and creator of VeeCon – a contemporary super conference that converges business and pop culture with innovation and technology. In addition to running multiple businesses, Gary documents his daily life as a CEO through his social media channels, which have more than 44 million followers and garner over 300 million monthly impressions/views across all platforms. His podcast, "The GaryVee Audio Experience," ranks among the top podcasts globally.

Gary serves on the board of MikMak, Bojangles Restaurants, Global Citizen Forum, and Pencils of Promise. He is also a longtime Well Member of charity: water.

Gary's life ambition is to buy the New York Jets.


[SCRUBBED] [4K] Watch Starship Flight 8, booster catch and Starship 2 test.

[TIME SUBJECT TO CHANGE] This is the eighth fully integrated test flight of Starship with its Super Heavy booster, the largest and most powerful rocket to ever fly. This is the second launch of the new Starship upper stage with many tweaks, bringing it closer to full functionality.

If all goes well, Starship will softly splashdown in the Indian Ocean about 66 minutes after it lifts off from Starbase, TX, having performed a Raptor relight test and deploying 4 Starlink mass simulators. SpaceX will hopefully be attempting to catch the Super Heavy booster with the launch tower again, which would be the third catch of the booster.

Want more information on how exactly they'll catch Super Heavy? WATCH THIS - https://www.youtube.com/watch?v=pAPt5vbr-YU
