I travel to Avondale a few times a year on business, and the hotel gyms have become pretty useless for the level I'm trying to train at. After some searching, I happened upon EOS Fitness as a solid candidate for a visit.
The facility is clean and well stocked with free weights and Hammer Strength machines. I was impressed by the friendliness and helpfulness of the staff. Overall I think this is a great location, and they have reasonable rates for short term guest passes. I'll definitely be back each time I visit Avondale for work.
