I believe a SkiErg is self-supporting. it has a large base.  I know its possible because I’ve seen it, but I cannot explain exactly how you position the skierg next to a treadmill.

as for alternatives: here is what I did.  about $100 worth of variable resistance pulleys and rope.  the pulleys flop around quite a bit the way they are positioned.  I have however devised a new setup that moves the pulleys too the floor and provides support for them, I just never made the change.  so yes this is a low dollar alternative and it works, just don’t expect the smooth operation found with a Skierg.

since these pics were taken, I added proper ski pole straps to the rope
