I love the Portsmouth location. I split my time between Stratham and Portsmouth as I workout with my kids. I get much more out of the portsmouth location, plus the people working there are great.
I joined in December as I am training for the West Highland Way in Scotland. I needed a tread mill to get my weekly miles in and a stair stepper for hill training. Planet Fitness was the perfect solution. It met all of my needs and there was always a treadmill or a stair stepper available for me every time I showed up.
