Uninterested is the opposite of interested. It simply means you have no interest in something:
He's totally uninterested in traveling. He likes where he lives and never wants to leave.
We approached the other company and proposed a partnership, but they were uninterested.
In casual spoken English, we tend to say "not interested" for the word uninterested.
The word disinterested means somebody is neutral. They have no bias (opinions that could unfairly influence their judgment). If two people are having an argument, they should present the case to a disinterested third party who can give a clear and fair evaluation of the situation.
However, some people do mistakenly use "disinterested" where "uninterested" would be more accurate.
Ergometer rowing machines colloquially ergs or ergo simulate the rowing action and provide a means of training on land when waterborne training is restricted, and of measuring rowing fitness. Ergometers do not simulate the lateral balance challenges, the exact resistance of water, or the exact motions of true rowing including the sweep of the oar handles. For that reason ergometer scores are generally not used as the sole selection criterion for crews, and technique training is limited to the basic body position and movements. However, this action can still allow a comparable workout to those experienced on the water.Indoor rowing has become popular as a sport in its own right with numerous indoor competitions and the annual World Championship CRASHB Sprints in Boston during the winter offseason.
