Could eccentric cycling be the key to easier fitness for sedentary people?

This study tested whether eccentric cycling (where you resist the pedals) is better than regular concentric cycling for improving muscle strength and fitness in sedentary adults. Forty-five healthy but inactive people were split into three groups: high-intensity eccentric interval training, moderate continuous eccentric training, or high-intensity concentric interval training. Researchers measured strength, aerobic power, and other health markers before and after 14 weeks of training.
