Question: Ordered a C2 yesterday. Now debating if I need the PVC mat. I have hardwood floors. I am planning to stick on some heavy duty felt pads. Good idea?
Document: I just bought my C2 and it is an awesome piece of equipment. Certainly the best cardio machine I've ever used. It's incredibly simple to use and incredibly hard to use well. You'll need a little practice before you can start ripping through a 2000m sprint, but odds are your heart and lungs won't mind you taking it slow.A word to the wise though:  Amazon (at least in my area) charges sales tax on this purchase. I ordered directly from Concept 2 and saved 80 bucks on sales tax.
I ordered this rower because I had been spending a lot of time on my exercise bike and was looking for a change. I had spent some time on a rower years ago and knew I enjoyed rowing. I'm 50+, in fairly good shape and not overweight, but after a lifetime of running my knees insist that I stick to "low impact" workouts.I ordered my Concept2 "D" on a Monday evening, it arrived in time to row on Thursday night.
I still have the original squeeze bottle of chain oil. It's good for sharpening knives, too. I just ordered a new shock cord yesterday from their website after seeing that mine is down to a few threads. The only other visible wear is a small chunk of foam cracked off of the edge of the seat. Honestly, after 20 years, that's it. Excellent piece of all American hardware.
We were looking for a heavy duty rowing machine and this is it. It is easy to use, was easy to set up. We would recommend this to our friends.
Great work-out, stores standing up and very easy to assemble. Well worth the money. Heavy duty and should last a long time.
We bought this to exercise in our NYC apt. It is very quiet and sturdy. We have it on a mat on top of hardwood and it does not move and no complaints from downstairs. I quit my gym membership and love the convenience of having this in our home. It takes up very little room.
While there may be some muscle soreness as one progresses, it disipates quickly if you stick with it. The foot pads are mounted on a wide bar which is part of the base. The construction is again solid and fluid so there is stability without any jerking or jarring motion. Ditto for the grip handle/bar which is connected to the drive wheel.The compelling feature that propelled me into using Concept2 is that it is kind to knees.
Looking forward to joining a virtual team online when I get a few meters under my belt.One cautionary statement, I can see where someone with back problems might really need to be careful with their posture and form. Lots of stomach exercises really hurt my back, so I was worried when I felt my lower back getting fatigued, but I stayed aware of my posture and it is okay this morning.
Okay, this is where you will find me totally crazy. There are actually indoor rowing championships. Amazon won't let me post the link, but on the C2 website go to /home/racing/calendar. I found a local event in my area and immediately signed up for a 500m race the same day I ordered the rower.
Be sure to buy the mat for it to sit on. After 6 months of frequent use, all is good.
Answer: yes
