Ken Nosaka backs eccentric exercise as a lower-effort, effective workout

In a Journal of Sport and Health Science opinion article, he says muscle-lengthening moves such as descending stairs or lowering weights build force while using less energy.
Nosaka argues soreness can be reduced by gradually increasing intensity and repeating exercises, making the approach accessible for older adults, sedentary people and some with restrictive health conditions.
He cites evidence including a 2017 study of 30 elderly obese women, where walking downstairs for 12 weeks improved heart rate, blood pressure and other fitness markers more than upstairs walking.

This exercise is ideal for the elderly, but can elite athletes also use it to unlock new performance peaks?

This method promises strength without exhaustion, but can it effectively compete with cardio for weight loss?

If this 'less is more' workout builds muscle so efficiently, will it make traditional gyms obsolete?
