Here's a response from a rower.
I rowed at UBC for one year. It was a lot of fun, but also a lot of pain. It also kinda fscked up my school work pretty badly.
Here's a typical week:
Monday, Tuesday, Thursday, Friday: Row on the water from 5:30 to 7:30 am. Go to class all day. Row in the gym from 5:30 to 6:30, do a 10 km run, 30 minute ab workout, get home at ~8:00.
(note: after the rowing workout, expect to throw up about 20% of the time)
Wednesdays: Same as above, just no scheduled team row in the afternoon. We were expedted to do something ourselves though.
Saturdays: Row on the water from 8 am until noon.
Sundays: No team practice, but we were expected to do something physical like running, biking etc.
Your hands will blister up REALLY badly. As one of my coaches said: "You'll eventually get rough, blistered, calloused hands. Girls love it when you rub them on their breasts."
Also, I was doing a combined honours physics/astro degree... my marks went down the tube. There was one engineer, one bio guy, and all the rest were human kinetics (read: university gym) students.
As for what it requires, cardio is huge. I mean HUGE. That was the main place where I lacked (although it builds up VERY quickly...). Despite the fact that I could do a 10 km run in about 40 minutes while laughing and talking (and singing hehe), my cardio was still pretty weak. My low rate power erg scores were best on the novice team (and were decent by the JV standards), but once we got into the intense high rate stuff, my scores became average.
Strong legs are big too, as are strong shoulders/back. (you don't have to be the Hulk when you start of course... they'll work on it with you).
Also, it's VERY frustrating your first few weeks out as it's very difficult to get the stroke just right. There are varsity guys who have rowed for 4 years and are in the national training program here that still have to work on it. Getting your crew to row in time takes time.
But, if you can deal with all of this, it's definitely very rewarding. You'll be in the best shape of your life, have a ripped body the girls will love, and then there's the experience. We rowed some late fall mornings here in Vancouver in the waters just beside downtown. We started before all the boat traffic was out on water that looked like glass. The sun was just about to come up, and we really got going right at sunrise. I tell you there's nothing like practicing a racing start at sunrise while rowing bow seat (me hehe).
The coach calls out ready. Everyone sits up half slide, all tensed and ready to go. You can see 8 puffs of breath in the morning cold just ahead of you. Then the coach yells out ROW! You slam your heels down and pull like crazy. Everything stands still for what seems like 5 seconds, but is really only half a second. All 8 oars then let out a loud snap and jiggle as they pop out of the water, the slides rush back, the oars click into place, and it happens again... After the first 24 strokes, the boat is just flying along, and all you hear is chunk, woooshhhhhh.... chunk, whoooosshhhh... You feel it burn for the full 2000 metres, then puke your guts out the side of the boat... It's the best
