How do you injury-proof your treadmill workout?
1) Don’t skip your warm-up. Being indoors, you might already feel warm and want to dive straight into your workout. But getting your blood flowing and your muscles warm beforehand lessens the impact on your joints and strain on your heart and lungs.
2) Run like you’re outside. Poor indoor technique habits – like running with slapping or thumping feet – can rattle your whole body. Practice the outdoor running style by landing lightly on the balls of your feet. Lean slightly forward but keep your shoulders back. And maintain a proper eye line – glancing down at your monitor instead of stooping to read it.
