We all get those aches and pains in our knees after pounding the pavement or running on a treadmill. The rower is a bit more forgiving. It’s low impact, which means it’s gentler on the joints. And in addition to working the same leg muscles as running, the rowing machine also targets our deltoids, biceps, abs, and erectors in our back. More muscles, same great cardio? Picking the rower over the treadmill is a no-brainer. The added benefit of rowing from a seated position allows for better venous return, meaning your blood returns to your heart quicker, which in turn allows for a greater cardiac output.
