Questions
Good to know
Quick answers about classes, getting started and what to bring.
What makes HIIT West Hampstead different from a traditional gym?
HIIT WH gym focuses on structured High-Intensity Interval Training classes designed to burn calories efficiently and build functional strength in short, effective sessions, unlike traditional gyms where workouts are often self-directed.
What classes can you do at the gym?
At HIIT West Hampstead you can train in seven coach-led HIIT classes: Ass n Abs, Boxing, Circuits, Energy, Hyrox, Power and Strength. We also run two small group personal training (SGPT) sessions, Hinge and Push and Squat and Pull, as well as baby fitness classes, kids classes and hen fitness classes. Our HIIT and SGPT sessions are 45 minutes and every exercise can be scaled to your level.
How soon can I expect results from HIIT training?
Many members notice improvements in energy and stamina within weeks, with long-term changes in body composition as you stay consistent with classes and proper nutrition. HIIT’s intensity and afterburn effect support efficient calorie burn.
What should I bring to my first class?
Come in comfortable training clothes, bring a water bottle, towel and (if you’re using lockers) a padlock. That’s all you need!
What levels of membership do you offer?
We provide flexible plans including a 2-week Kickstart trial, monthly membership and pay-as-you-go options tailored to your fitness goals.
What is the most popular gym class?
HIIT (High-Intensity Interval Training) is one of the most popular types of gym class because it is fast, effective and easy to scale to your level. At HIIT West Hampstead that includes our Boxing, Circuits, Energy and Hyrox classes. We also offer baby fitness classes, kids classes and hen fitness sessions. Not sure where to start? Try a Kickstart and your coach will help you find your level.
What is the best type of workout class?
The best class depends on your goal. For improving fitness and endurance, HIIT is excellent. For flexibility and relaxation, yoga or Pilates is a good choice.
Which gym class is best for weight loss?
HIIT and spin classes are often best for weight loss as they burn a high number of calories in a short time. Attending regularly and eating a balanced diet are also important.
