A practice without any subscription, without any equipment and which can be easily integrated into daily life.
From a certain age, the rules of the game change. Many discover that long sports sessions or severe dietary restrictions no longer give the hoped-for results. The body, subjected to new constraints, becomes more resistant, slower to react. It is on this observation that a coach specializing in weight loss wanted to highlight a physical activity accessible to everyone and particularly to those over 40.
Indeed, Isaiah Fergusson, who has been supporting people in search of physical transformation for years, regularly observes the same scenario among those who cross the 40-year mark. Energy is no longer the same, metabolism slows down, recovery becomes more laborious. Yet the dominant recommendations in the sports industry continue to push in the same direction: repeated cardio sessions, high-intensity programs, reduced-calorie diets. However, according to him, this strategy is often counterproductive. In a video posted on his Instagram account on August 27, he explains why: “For decades, you’ve probably been told that to get results, you have to sweat more, push more, and burn more calories. But after 40, you have to adopt different rules.”
He reveals here that the stress accumulated by these extreme efforts acts directly on the ability to lose weight. The expected result – a gradual loss of fat mass – is thwarted by an organism saturated with contradictory signals. Instead of burning more, it stores more. “There’s more stress, more cortisol, more blood sugar swings, and all that hard work and pushing your weight during workouts only makes it worse.”he emphasizes. In his eyes, it is not a question of giving up physical activity, but of rethinking the way we approach it. Because if intensity no longer works in the same way after 40 years, other levers prove more powerful.
This neglected option, the expert defends it with conviction: walking. It requires no equipment, no room, no special training. It activates what the coach calls the “non-exercise-related thermogenesis”, a mechanism which would represent at least 30% of calories burned daily. Unlike demanding disciplines, walking does not overload the body, does not deplete energy reserves and does not cause hormonal backlash. In short, it acts as a regulator.
For Isaiah Fergusson, it is this regularity, accumulated day after day, that leads to real results. According to him, this practice constitutes the most neglected, but also the most effective, strategy for lasting weight loss after the age of 40.
