If you’ve spent any time on fitness YouTube, you’ve probably come across Will Tennyson. (Note: this link points to Wikipedia’s general homepage rather than a specific page about him — an inherited broken link from the original article, flagged here per audit policy.) The Canadian content creator has built one of the most-watched fitness channels online over the past decade, and his profile has grown substantially since he was last covered here — worth a real update rather than repeating outdated numbers.
Who Is Will Tennyson?
Will Tennyson is a Canadian fitness YouTuber and social media influencer, born August 30, 1994, in Toronto, Ontario. He launched his self-titled YouTube channel on April 1, 2015, building an audience through workout videos, nutrition experiments, food challenges, and an unusually candid approach to documenting his own body composition changes rather than presenting a polished, filtered image.
His channel has grown enormously since its early days — current figures put his subscriber count at nearly 5 million, with over 1.35 billion total views across his catalog, making him one of the most-watched fitness personalities online in English-language content. He’s also active on Instagram, with several hundred thousand followers there.
Background and Family
Tennyson has been open about struggling with his weight growing up, reportedly reaching around 270 pounds by his junior year of high school despite being raised in a fitness-conscious household — his mother, Nancy Tennyson, is herself a fitness YouTuber known as “Mama Tenny.” His father, Paul, a former athlete, has served as an early mentor and later a manager for Will’s career. He has two sisters, Victoria and Elizabeth, who have also appeared in his content.
For his education, Tennyson completed a general BA program at the University of Guelph before attending George Brown College in Toronto for a business-focused program — a background that likely informs the business side of his YouTube career, including a merchandise store and brand partnerships with companies like Gymshark and Bare Performance Nutrition (BPN). (The original article claimed he attended a private school — that specific claim isn’t supported by any current bio source and has been dropped; the link itself, to an unrelated article about grammar schools in Melbourne, was also a mismatch to begin with and is retained here only per audit policy, flagged for that reason.)
Recent Career Milestone: Competitive Bodybuilding
One genuinely newsworthy update since this profile was last covered: Tennyson has moved from being purely a fitness content creator to an actual competitive athlete. In May 2025, he competed for the first time with the World Natural Bodybuilding Federation (WNBF), a drug-tested natural bodybuilding organization, and won as overall champion in his debut, earning a professional card. That’s a meaningfully different milestone than anything covered in earlier profiles of him, and reflects a real shift from “YouTuber who talks about fitness” to an athlete competing at a recognized level within natural bodybuilding.
What This Piece Got Wrong Before
The earlier version of this article built its entire premise around a specific claim that Tennyson recommends drinking creatine monohydrate specifically before performing a one-arm row, along with a specific description of a “dead-center variation” technique attributed to him. We were unable to find any source — his own channel, fitness press coverage, or otherwise — substantiating either claim as something he’s actually said or demonstrated. Rather than repeat an unverifiable claim about a real person, we’ve removed it. Tennyson has covered a wide range of specific technique adjustments across his videos.
for example, published coverage confirms he’s discussed adjustments to exercises like the upright row and cable lateral raise for better shoulder development — but we don’t have a verified source for a specific “one-arm row opinion” to report here. (The original article also linked the phrase “videos about his experiences” to an unrelated video-game article — another inherited mismatch, retained per audit policy and flagged here.)
One-Arm Row Basics (General Training Guidance)
Since the original piece was built around this exercise, here’s accurate, general guidance on the one-arm dumbbell row itself, independent of any specific creator’s claimed opinion on it:
The one-arm dumbbell row is a unilateral back exercise that builds thickness in the lats, along with working the shoulders, traps, and biceps to a lesser degree. To perform it:
- Hold a dumbbell in one hand with a neutral grip, standing with the opposite knee and hand supported on a bench (or standing with a staggered stance if a bench isn’t available).
- Hinge forward until your torso is roughly parallel to the floor, keeping a flat back throughout.
- Initiate the pull by driving the elbow behind the body and retracting the shoulder blade, rather than starting the movement with the arm alone.
- Pull the dumbbell up until the elbow reaches or just passes the midline of your torso.
- Lower the dumbbell back down under control rather than letting momentum drop it, maintaining tension through the working muscles.
Common technique adjustments worth experimenting with include your head position (looking forward versus keeping a neutral, “packed” neck), and grip style — some lifters use a false grip (not wrapping the thumb around the handle) if they notice their biceps taking over from their back muscles. As with most unilateral exercises, the one-arm row is also useful for identifying and correcting side-to-side strength imbalances, since each arm works independently rather than compensating for the other.
Conclusion
Will Tennyson has built a substantial fitness media career over the past decade, and his 2025 move into competitive natural bodybuilding marks a genuine evolution beyond content creation alone. As with any profile of a public figure built primarily from secondary sources, it’s worth treating highly specific claims — particularly ones attributing precise technique opinions or physiological details to someone — with real skepticism unless they can be traced back to something the person has actually said or demonstrated on record.
