Our classes

We offer a wide variety of classes that cater to different schedules and fitness levels. Our timetable boasts 20 different classes per week, ranging from high-intensity interval training to strength and functional fitness.

Each class is 45 minutes long and includes a full warm-up and cool-down session.

Our instructors use a 3-tier fitness scale to provide options for exercises that cater to varying abilities, so everyone can get the most out of their workout. We use a range of equipment, including kettlebells, barbells, battle ropes, and medicine balls, to add variety to our classes.

The meeting point for all classes is next to the D-Day Museum on Clarence Esplanade, and any changes to the meeting point will be shared on our social media profiles.

We’re fully insured, so you can have peace of mind while you work out with us. Join us today and discover the perfect workout routine for you!

    POF is a great way to get fit, meet new people and get outside. It’s such a lovely community and the classes go really fast. Tristam is so positive and even though there is often many people in a group, he will always correct your form and encourage you throughout. It’s like having a PT but in a group. Best decision I have made fitness wise.

    I have been to so many gyms over the years and never felt motivated to go. POF changed my view of fitness and motivated me to keep on improving. It is definitely the best fitness group around and the community feel is an added bonus. Would highly recommend going.
