I have used a rowing machine for decades, and am fortunate to now have one in my home, a Concept2. I have seldom used their Ski Erg, and found this review useful. He is spot-on about the quality of Concept2 products.
Anybody out their use the Ski Erg?
I'm sure he's paid to give positive marks on that machine; he sound's too "in love" with it.
I'm not impressed with the direction of resistance (pulling downward).
My go-to workout machine that is the simplest, has the greatest variety of directional resistance pulls and pushes is the "Total gym".
No wind nor water resistance device.
Simple and helpful. I've been using the T.G. for decades.
