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?
Most gyms offer classes such as yoga, Pilates, spin (indoor cycling), HIIT, Zumba, strength training and circuit training. You can also find Gym Classes, Hen Fitness Class, Hyrox classes and HIIT Classes at many fitness centres across the UK.
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 classes because it is fast and effective. Many gyms now offer HIIT Classes, Hyrox Classes, Hen Fitness sessions and even a baby fitness class for new parents. Spin classes are also very popular across the UK.
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.
