Using a Rowing machine can give you a great workout and if you use the rowing machine for 30 minutes per day you can burn up to 300 to 350 calories per day.
I lost 20 lbs of weight in 2 months of using the rowing machine 30 minutes per day doing a good workout and the harder you workout on the rowing machine the more calories you'll burn off and the more weight you'll lose.
The rowing machine will also give you a good cardio workout as well so you'll improve your heart health and cardio health as well.
Working out on a rowing machine can help you stay fit and active over the years and help you live a very long healthy life.
