Passing by sioux falls for the day and I was looking to get a quick pump . The owner set me up with a day pass fast. The gym was not staffed. But no worries at all the owner buzzed me in remotely after the payment. This is the exact atmosphere I want in a gym. No fluff straight to the point. Come here and pump some iron.

A little gym geared towards lifters. A good mix of equipment which looked weighted towards powerlifters. The owner, Jared, was flexible in gettimg me access on a guest pass.
