Errors that are easily committed by maturing people who seek fitness through rowing.

To me it is crystal clear that the aging clock can be slowed down, way down, with the right training plan.
The greatest errors committed for "aging" people who work out and look for greater fitness are: intensity that is too high, too little torque, too little mileage, unknown target heart rate, technique that does not utilize the major muscle groups which restricts range of motion and can lead to injury.
