Bryan Johnson
Bryan Johnson, widely known for his ambitious anti-ageing experiments and health-focused lifestyle, has stirred fresh debate in the fitness and wellness community. In a recent statement, Johnson claimed that performing just 10 squats at intervals could be more effective than taking a traditional 30-minute walk after meals—challenging long-standing health advice.
For years, experts have recommended a short walk after eating to help regulate blood sugar levels and support heart health. However, Johnson believes there may be a more efficient alternative, especially for those with busy schedules.
The Claim: Short Bursts vs Long Walks
According to Johnson, doing 10 squats every 45 minutes can outperform a continuous 30-minute walk when it comes to managing post-meal blood sugar. He referenced a 2024 study titled “Enhanced muscle activity during interrupted sitting improves glycemic control in overweight and obese men” to support his claim.
He explained that the advantage lies in activating large muscle groups repeatedly throughout the day rather than relying on a single, extended activity session. This repeated activation, he argues, helps the body process glucose more effectively.
The Science Behind It
Johnson highlighted the role of major muscle groups like the quadriceps and glutes, describing them as the body’s largest “glucose sponges.” When these muscles are engaged through exercises like squats, they absorb more glucose from the bloodstream, helping to stabilize blood sugar levels.
The idea is simple: instead of sitting for long hours and then going for a single walk, breaking up sedentary time with short bursts of activity can keep the metabolism more active throughout the day.
However, Johnson later clarified an important detail. The reported 14% improvement in blood sugar control was not exclusively due to squats alone. Instead, the benefit came from interrupting long periods of sitting every 45 minutes—whether through squats or short walks.
What the Study Actually Suggests
The study Johnson cited emphasizes that frequent movement is key. Participants who took short, regular activity breaks—either walking or performing simple exercises—showed better blood sugar control compared to those who completed one longer walking session and then remained sedentary.
Researchers concluded that these benefits likely come from increased muscle activity during repeated transitions from sitting to movement. In other words, consistency matters more than intensity alone.
This insight aligns with a growing body of research suggesting that prolonged sitting can negatively impact metabolism, even if you exercise later in the day.
Social Media Buzz and Public Reaction
Johnson’s statement quickly gained traction online, sparking mixed reactions. Many users appreciated the practicality of his suggestion, especially those who struggle to find time for a dedicated walk after meals.
Some social media users described the idea as “simple yet highly effective,” while others noted that it could be a convenient alternative for people with desk jobs or tight schedules.
Others pointed out a broader takeaway: staying active throughout the day may be more important than focusing on a single workout session. For instance, getting up every hour to perform a few squats or take a short walk could help reduce blood sugar spikes more effectively than remaining inactive for long stretches.
10 squats beats a 30 min walk.
For blood sugar control after a meal, doing 10 squats every 45 minutes outperforms a dedicated 30 min walk by 14%.

A Balanced Perspective
While Johnson’s claim has generated excitement, it’s important to view it in context. Traditional walking still offers numerous benefits, including improved cardiovascular health, stress reduction, and overall fitness.
Rather than replacing one habit with another, experts suggest combining both approaches—incorporating regular movement breaks along with longer exercise sessions when possible.
Bryan Johnson’s perspective highlights an important shift in how we think about fitness and health. It’s not just about how long you exercise, but how often you move throughout the day.
Whether it’s squats, short walks, or simple stretches, breaking up long periods of sitting could play a crucial role in maintaining better metabolic health. For many people, this approach may be easier to adopt—and more sustainable in the long run.
