Would be pretty cool have a machine like this in the basement and keep it at a casual pace….simulate a skin accent of your favorite backcountry zone while watching Netflix but taking it to the red zone and leaving it there it like 2016 & 2018 ISMF World Cup Winner Michele Boscacci is a pure sufferfest, puke bucket territory. Madness.
