    Not open until 7 on Saturday. I’m used to at least 6 or 5. That’s too late. Many prefer to start earlier. One exercise bench inoperable: handle missing to adjust height. Woman at desk quite pleasant. Well appointed.

    This a larger planet fitness compared to others I frequent in the central Jersey area. There are plenty of free weights and benches but of course could always be a couple of more. I like the aerobic area in the back and the machines strategically placed where creeps can’t stare at you. The staff is generally okay but some are better than others in regards to cleanliness. Some workers rarely leave their perch behind the counter (on their phones of course); while others are always cleaning or replenishing wipes spray bottles and cleaning etc. Maybe overall PF can find a way to get people to not sit in machines and watch videos or talk on their phones! Plenty of cardio machines and one is always available. Machines are rarely broken and are fixed quickly. Not sure why PF overall doesn’t retail sell power /protein bars etc as well as powders and more kinds of health drinks. I believe this would be quite lucrative. Overall this is one of the better PFs I have visited.
