The Ironman Training Thread 2024

Random question that I’m reminded of by this thread: One cross training device to rule them all - skierg vs rower?

Have any of you used a SkiErg as a cross-training tool for swimming, specifically? I don’t have any space left for a rower or a swim erg, but I might be able to fit in a SkiErg, and the movement and muscle involvement seems at first glance like it’d be complementary to swimming, but I’m curious if any of you have first hand experience with it.
