Well here's my situation...
Wife and I are 32, I've been into serious fitness since I was 12, and right now we have a garage gym w a barbell, bumper plates and steel up to 500 lbs, squat stands, pull-up bar and rings, bench, kettlebell, weight vest, sled for dragging, and an air dyne bike. I also try to run hills once every couple weeks and trying to do it more recently again. I will never not workout, and am typically trying my best to make it all better.
Recently I have been considering the idea of getting a concept 2 rower as it seems right up my alley. However, I have been and still am on a mission to pay off our house in 5 more years (I know I know, but that's for a different topic). I guess what I'm wondering is, is there a point where as just an average citizen trying to be strong and conditioned that you just need to say enough is enough w your tools for fitness? Yes I would love the rower but what will it do for me that going out running up hills or sled dragging or going for a long run or getting on the air dyne can't do for me?
I suppose I'm looking for someone to tell me it'd be a great investment or it's not necessary at all.
