Boring, but not extremely hard. You can make it so, but I normally do intervals of slow @ 26 rows per minute, moderate @ 28-29 rows per minute and then hard at 33-34 rows per minute. Hard for me anyway.
Also change the resistance from 5.5 and on occasion up to 10. Having something interesting to watch on the tube makes it go fairly quick.
Did hit a one time row the other day of 2:07 for 500meters. Goal is to bust thru the 2minute mark you mentioned.
