I bought one a few years back. Love it, but it is by far one of the most strenuous exercises I do. 15-20 minutes on that thing, if you row hard, is a killer even though I kayak frequently and go for hours. I know they are expensive, but don't buy a cheap one. I waited until I found a deal on a used concept 2 and have no regrets. I've tried a few other models and they don't compare IMO. That said, I haven't tried every model out there.
Stronglifts.com
Or do Starting Strength.
Either way, that's been fantastic and I finally got rid of my "played soccer in HS" body and can lift things like someone who goes to the gym now.
I don't like machines, getting under a barbell or kettlebell works better, since you're working your stabilizing muscles.
Yeah a rowing machine is to a canoe as a treadmill is to jogging, I don't think the typical downsides to weight machines apply the same way.
That said, I am in 100% agreement with you when talking about Smith machine, all the various pulley machines, etc. No real upside except a more pure isolation, and even then you only really need that isolation if you're bodybuilding (once you've built up a solid strength base).
Actually, what I've found is a rowing machine is more like sculling than canoeing or kayaking. Sculling is a continuous workout with no real rest and it engages legs, arms, shoulders, back, core, etc.. Kayaking/canoeing really doesn't engage the legs at all, and the core to a lesser extent as well, but I digress.
Stronglifts was great for me, back when I gave a **** about my body.
So you are saying a rowing machine doesn't work your stabilizing muscles? If not, then you aren't doing it right.
Of course weights will be superior for muscle and strength gains, but when it comes to a full body workout that includes aerobic gains, a rowing machine is superior. I'm not suggesting you can't lift weights and separately do aerobic exercise, you very well can and that would be the best of both worlds, but if I only have 30 minutes, the rowing machine is the way to go. Legs, core, back, shoulders, arms, etc... all get into the act.
I'm talking Smith Machines in general
Running.
Lots and lots of running.
