Frog's has been my gym for over a year now and it's great. Not really a whole lot of amenities (spa, towel service, whatever)...but for those who just want a bare bones gym with all the necessary equipment/weights at a fair membership fee then Frog's is it.
The owner Vito is awesome too...great fella, and the family owned vibe is a strong contrast to big commercial gyms.
Only got 4 stars because the hours on the weekend are short.
