The Landmark Study Explained
Researchers recently published findings in the British Journal of Sports Medicine based on an analysis of three major long-term health studies. These studies followed 147,374 men and women for up to 30 years, periodically asking them about their exercise
habits, including both aerobic activity and muscle-strengthening exercises. By tracking this data over decades and noting mortality outcomes, scientists were able to identify powerful connections between specific exercise durations and long-term health, offering a clearer picture of the role resistance training plays in longevity.
The 90-to-120-Minute Sweet Spot
The study's most significant finding was the identification of a weekly "sweet spot" for strength training. Participants who performed 90 to 119 minutes of resistance exercise per week showed a 13% lower risk of death from any cause compared to those who did none. The benefits didn't stop there. This same time frame was associated with a 19% lower risk of dying from cardiovascular disease and a 27% lower risk of death from neurological diseases like dementia. Interestingly, the researchers found that doing more than 120 minutes per week did not provide any additional reduction in mortality risk, suggesting this is an optimal range for maximizing benefits.
What Counts As Strength Training?
You don't need a high-end gym membership to meet these guidelines. The study considered a wide range of muscle-strengthening activities. This includes traditional weightlifting, but also highly accessible bodyweight exercises like push-ups, squats, and lunges. Activities like using resistance bands or even some forms of heavy gardening can contribute to your weekly total. The key is to engage in activities that challenge your muscles and force them to work against an opposing force or weight. Experts note that you can break up this time into shorter, more manageable sessions throughout the week to reach the goal.
The Power of Combination
While 90-120 minutes of strength work alone is beneficial, the study confirmed that the greatest longevity boost comes from combining it with aerobic exercise. Participants who paired regular strength training with adequate aerobic activity—like brisk walking, running, or cycling—saw the most dramatic results. The lowest overall mortality risk was found in those who combined 60 to 119 minutes of weekly strength training with high levels of aerobic activity, resulting in a risk of death up to 45% lower than those who did neither. This reinforces the message that a well-rounded fitness plan incorporating both cardio and strength is the most effective strategy for a long and healthy life.
Putting It Into Practice
Hitting a target of 90 minutes a week can feel achievable. It could be broken down into three 30-minute sessions or two 45-minute sessions. For someone just starting, the key message from experts is that even small amounts matter. Beginning with two 20-minute bodyweight workouts a week and gradually building from there is a great strategy. The study highlights that consistency over the long term is what drives the health benefits. Finding a routine you can stick with is more important than trying to do too much too soon. The goal is to build a habit that supports your health for decades to come, and this research gives a clear and effective target to aim for.
