If I had to buy one right now, I'd choose the Rogue Echo Rower over the C2 Row Erg, and it all comes down to the larger wheels to make maneuverability better and the easily fold for better storage. The C2 might have the slightly better monitor, but both are good once you get the hang of each. If you never tried the C2, the Echo Rower would easily top the list of row ergs out there, so it all comes down to the other things when comparing the two models. Can't go wrong either way.

Of all the air-bike cardio tools, the Rogue Echo bike is the best built and the least forgiving. It stops the most quickly once you quite pedaling, so racking up calories requires every last bit of effort. It's very sturdy, and it's basically the go-to unit for even commercial gyms. However, (in my incorrect opinion) air-bikes are not great for steady-state, long duration cardio, so the value is limited by what is a essentially single use cardio machine.

The C2 is the baseline that all rowers get compared to because there is almost nothing better than it. I currently don't have a rower, but it comes back to being my favorite form of cardio, and the C2 is top of the line. It is pricey, however, but you get good quality for that price. I would also like to be have bigger wheels and a bit easier to stow, but those are really the only complaints.

I like these for various exercises. I have even found a way to use these for rear delt flyes and hamstring curls. The handle isn't super comfortable however, and I wish they have an odd number if loops so I could hook up the middle of the daisy chain using one loop instead of two.

I like these spotter arms more from a functional standpoint than the Rep PR-4000 ones. Although I don't move them all that often, I like these better than the ones where I have to twist and pull out because of the Athena cable attachment I have. The build quality isn't quite as good as the Rep ones because these only have UHMW tape on the inside, but functionality wise, they're worth it in my opinion. Even though they take up the same number of holes on the rack, the actual spotter part of the arm sits about two inches lower than Rep spotter arms because of where the arm is centered. I like that feature. With the scratch and dent discount, the price was great for this functionality.

A single arm pressing attachment for a landmine. I bought this to help train for a esoteric strongman event at a competition I go to yearly even though the pressing event itself probably won't be around much longer in its current form. However, this is an okay handle to use for pressing if you don't want to hold on to the barbell directly. Stick with the 1.9" diameter. A 1.3" diameter exists, but it will feel worse for pressing. Additionally, although there is not explicit weight limit mentioned, it's definitely at most 400 lbs when I tried to use it to simulate a one arm deadlift. The tightening pin will fail before any actual welds do, especially if you tighten if from the bottom. However, I did buy a second one to replace my broken one because it wasn't really that expensive if it's on sale. Update: after receiving my second handle, I had to file the hole because the screw wouldn't fit all the way. I was able to do it, but I needed to reduce the build quality rating by one star.

I can do dips on it. When I had a Rogue Monster Lite rack, it was fine without the UHMW due to the powder coat of the RML Flat foot rack. However, I hesitate to use it on a Rep PR-4000 with the different coating. I will likely have to add UHMW tape before utilizing it some more.

Great log. One I miss using now that I don't have a gym membership. If I see it pop up for sale, I will buy it.
