As a former rower (who now plays squash recreationally), rowing will build you into a ridiculous athlete. You'll be extremely fit in it's most complete sense. You'll be able to run, cycle, erg (rowing machine), and lift pretty serious weight in the gym. Jack of all trades maybe, but your actual rowing will develop over time and the camaraderie is second to none. It surely has to be one of the most brutal sports. I was pretty short so couldn't get a good reach, but I added technique and power to the boat. If I was taller I would of been a bit more competitive and maybe stuck at it. The training was 7 - 10 times a week, at like 5:45am starts some days so I just couldn't handle it. Because of this, as somebody else said before, squash is infinitely more fun. Rowing is a tough sport to enjoy. It's extremely monotonous. Summer training where you're on the water is a lot more and the you do more sprint work (500m sprints and harder 2ks as opposed to a steady state 5k+) and practicing racing starts/racing in general is really enjoyable..and maybe...just maybe balances out the grueling winter training. Racing at proper regattas is really fun, it was basically going away for a weekend, doing the races (2k races are amazing) and then getting pissed. Girls that row are hot.
