Researchers found that not performing repetitions to failure may be more effective at increasing muscle size and endurance in untrained individuals.
Brain Fitness Versus Physical Fitness for Healthy Aging
Cognitive capacities influence physical activity levels more than vice versa, so people with healthier brain functioning are more likely to be active.
Compound Lower-Body Exercises Build More Strength

Some Physical Activity May Not Benefit Heart Health
Resistance training may reduce fat levels around the heart (above), but not all strength-based activities are beneficial for cardiovascular health. New research shows that occupational activities like routinely carrying heavy loads at work may have a negative impact on the heart.
Strength Training Reduces Heart Fat
Location matters with body fat. The accumulation of excess fat around the heart can increase the risk of cardiovascular disease. A new study by researchers at the University of Copenhagen in Denmark assigned participants to resistance training, high-intensity interval endurance training (HIIT) or no exercise. Results showed that only people who lifted weights decreased the fat lying closest to the heart—specifically, inside the sac that encases the heart (the pericardium).
Build Fitness Without Demolishing Joints
High-impact exercises — such as burpees, jumping jacks and other moves that get both feet off the ground simultaneously — can help build strength and endurance and shed fat quickly.
As a result, they’re often incorporated into high-intensity interval training (HIIT) workouts, which have gained recognition because they burn an impressive number of calories in a short amount of time and boost metabolism for up to 48 hours after the workout’s over through the afterburn effect.
