I want to know if you have excise equipment like a stasionary bike

Its a thrift store!!!

There is exercise equipment frequently. Stock is added multiple times during the day every day.

Its best to check inventory weekly

Their stock is dependent on whatever people donate which wildly varies. I would suggest call and express an interest in item(s) you want and sometimes they'll call when that item is donated but this isn't guaranteed.

I seen one there mths ago,cant promise its still there

Sometimes they do. It all depends on what gets donated that week
