This is the ROWBRO: a Bluetooth connected rowing machine that fits in small homes and can give you a solid workout every time. It weighs only 26lbs, so you can easily move it around. It also has a pull-up bar to work your biceps. This rower machine can handle users up to 256lbs.
ROWBRO has adjustable magnetic resistance. It combines with the ROWBRO app to keep track of your rowing progress. The app is available for iOS and Android devices. To get started, simply put the ROWBRO in your doorframe, secure it with the pull up bar, attach the guide rail, and place the seat on it. This project can be found on Indiegogo at this time.[where to get it]
