Brian Shaw believes one bad decision should never define an entire week, month, or even a person’s identity.
The four-time World’s Strongest Man opened up about the importance of “positive momentum” while discussing mindset, discipline, and the way people often spiral after a setback.
For Shaw, the biggest mistake people make is allowing one off-track moment to completely derail their progress.
“I’m a big fan of building positive momentum,” Shaw explained. “Positive momentum can carry you very, very far.”
It’s a mindset that applies far beyond training or fitness challenges.
According to Shaw, many people fall into an “all or none” mentality, especially when they’re trying to improve their lifestyle or transform their habits. One difficult day quickly becomes an excuse to abandon everything altogether.
He used a relatable example that many people experience after a long week.
“Maybe they’re going through some type of transformation challenge, right? Weekend comes, Friday night, friends, drinks, eat bad food, whatever they go way overboard, way off the rail,” Shaw said.
But instead of treating that one evening as a temporary mistake, Shaw believes people often mentally surrender the entire weekend before it’s even happened.
“Instead of understanding that Friday or Saturday is now done, you can wake up the exact next day and start the day great and start to get right back on,” he explained.
That ability to reset immediately, rather than dwelling on guilt or frustration, is where Shaw believes real growth happens.
At the centre of his message was one line that perfectly summed up his outlook on self-improvement.
“You’re not your past; you’re not, you’re not at all,” Shaw said.
For Shaw, carrying yesterday’s mistakes into today only creates unnecessary damage. The real danger isn’t the single bad meal, missed workout, or night out — it’s the defeated mindset that follows afterwards.
Instead, he warned against the mental spiral that causes people to completely lose control after one setback.
“But instead it’s like, oh man, Saturday’s going to blend into Sunday, and it’s wasted energy, wasted energy, defeated mindset and then it’s the whole next week is off, then the whole next month is off.”
It’s a mentality Shaw has clearly seen repeatedly, both in fitness and in life more broadly.
His point wasn’t about perfection. It was about response.
A bad day does not automatically become a bad week unless somebody allows it to. Shaw’s message focused on the power of immediately regaining control rather than punishing yourself mentally for slipping up.
The concept of “positive momentum” has long been associated with elite athletes, but Shaw framed it in a way that feels accessible to almost anyone. Small wins stack together. One good decision leads to another. Momentum builds quietly until discipline becomes easier to maintain.
Equally, negative momentum can work in exactly the same way.
One careless decision can become two. Then three. Then suddenly, an entire month has disappeared under the weight of frustration and self-defeat.
Shaw’s advice cuts through that cycle with a much simpler approach: restart immediately.
No dramatic reset. No waiting until Monday. No writing off an entire weekend because of one night.
Just begin again.
The message also reflects the mindset that helped Shaw reach the top of strength sports for so many years. Consistency, recovery, discipline, and resilience are rarely about being perfect every single day. They’re about limiting damage when things go wrong and refusing to let temporary setbacks become permanent habits.
