90 to 120 Minutes of Strength Training Per Week Linked to Longer Life and Better Heart Health, Study Finds
New research shows that 90 to 120 minutes of strength training per week is associated with improved longevity and cardiovascular health. The findings add to a growing body of evidence that resistance exercise is as important as aerobic activity for long-term health.
Researchers have found that 90 to 120 minutes of strength training per week is associated with better longevity and cardiovascular health outcomes. The findings, highlighted in 2026 health research reviews, add weight to the case for resistance exercise as a core part of any wellness routine.
The research suggests that two to three strength sessions per week, each lasting 45 to 60 minutes, is enough to produce meaningful health benefits. Participants who trained in that range showed lower rates of cardiovascular disease and better markers of metabolic health compared to those who did no resistance training.
Strength training builds and maintains muscle mass, which declines naturally with age. Muscle loss is linked to a range of health problems, including insulin resistance, falls, and reduced mobility. Resistance exercise also improves bone density, which matters especially for women after menopause.
Experts recommend pushing muscles toward fatigue during each session to get the full benefit. That does not require heavy weights. Bodyweight exercises, resistance bands, and moderate dumbbells can all produce the necessary stimulus.
The findings align with guidance from Stanford Medicine, which recommends that adults in their 20s and 30s build strength training habits early to protect their health in later decades. The earlier the habit starts, the more protective the effect.
Aerobic exercise remains important. The research does not suggest replacing cardio with weights. Instead, experts recommend combining both: 150 to 300 minutes of moderate aerobic activity per week alongside two or more strength sessions.
