Absolutely everything you need for a challenging workout. The staff is amazing and I’ve met some wonderful people."

"I love Onslow [Fitness]... The equipment is great and it is not too crowded, it seems they have found a way to space things pretty well. I also love that it is available 24 hours. The daycare is wonderful and I love the video screen showing you the daycare where they don't know your watching. Creates a secure feeling. Great place to be!"

"My family and I have been members of Onslow Fitness for 2+ years now. I have to say it is a great gym. The environment is welcoming and upbeat. The staff is always friendly and open to giving advice to anyone who seeks it. The gym facility itself offers practically anything you would want in a gym environment. Overall I'd recommend OF to anyone! It has something for people of all fitness levels. If you aren't sold yet by the reviews from everyone don't hesitate to capitalize on the Free Pass they offer via the Onslow Fitness website. Check it out, you will not be disappointed!"
