We don't need a stair-master machine at our house.
It's called fire wood collection
Load container with about 15kgs of wood
Climb up the hill carrying said load of wood (excuse my cleavage)
This is not a butt blaster, its a back blaster.
I have to give big ups to my husband who spent 4 hours chainsawing our trees so we could stay warm for another couple of weeks.
