After 7 years, the ergometer (a.k.a. rowing machine) is still, by far, the best workout I’ve ever had at a gym.

I used to be on the crew team in high school and one of the most common on-land exercises was to do agility and endurance tests using the erg. What I love about the erg is that it works so many parts of your body at once (arms, shoulders, legs, abs, etc.). Additionally, it can really help improve your rowing form.

If you need to burn calories, this is definitely one avenue you need to consider.
