Depending on what are you doing on a rowing practice, but certanly A LOT!
Depends on the intensity.
Are you referring to on the water rowing, or rowing indoors on an ergometer? Both burn calories at a very rapid rate. On a concept 2 erg machine, you can select a screen that displays the number of calories per hour. On the water, it is a bit harder to gauge, but if you plan on rowing competitively, you can easily burn over 1000 calories in a 2-3 hour session. From my experience as a varsity collegiate rower, throughout our rigorous two-a-day practice sessions, it is necessary to consume nearly 5000 calories a day, and weight can still be lost. Depending on the level you seek to row at, you can easily burn a huge amount of calories.
20 minutes is around about 1 mars bar
It depends on how long you use each machine. Rowing machines are primarily used for strength development. Because of this, they do not burn many calories at once. However, they serve a different purpose of building calorie-burning muscle.
First you should make sure it is healthy for someone of your sex, height, and body type to lose that much weight. If you are currently overweight and can safely lose 28 lbs, then this is feasible and will likely take between 4 and 6 months. First you'll need to assess how many calories you burn during an interval of exercise on a rowing machine. Most machines will tell you how many calories you've burned during a session. One pound of fat is about 3,500 calories. If you burn 100 calories in 10 minutes of rowing, and you row for 350 minutes a week, then you'll lose 1 pound a week just from rowing.
=how many records have australia set in rowing?=
About 2,000 calories or so.
The rowing machine manufactured by Nordic presumably will allow one using it to burn 1000 calories per hour. One would have to row very vigorously and consistently on this machine to reach that number!
