Yes to not liking the lunges either. On your 5K row, you averaged about 2 min/500m and is about where I usually am for longer rows. I'd say that's decent but far from good. Get that pace down around 1:45/500m for that long and you're getting into impressive.
I agree that rowing is boring, but I like doing it just not for near that long. Try doing a couple of 500m intervals but get that pace down in the 1:30s. You'd probably like this one: 3 rounds for distance
Row a 1:25 pace as long as possible Run 200m Rest 1 minute
Post total distance and time.
That sucked my lungs right out of my chest.
PS- TAK liked to row and give advice on it. hint. PPS- He never believed the times I posted.
