Taking a boat out for a spin really works the muscles and heart, but for most of the year we’d rather stay on dry land. Get all the benefits (and avoid the possibility of falling into a cold body of water!) with a session on the rowing machine, or ergometer. These machines build flexibility, full-body muscle strength, and cardiovascular endurance.

Do it Today: Today at the gym, take the rowing machine for a spin to exercise the whole body. Pro tip: ask a trainer to help nail down the correct form to avoid injury and get maximum benefit (it can be tricky to nail at first).
