8 of London’s Best Treadmill Workouts

The world’s original treadmill-based class now has four studios in London, all offering the same, sweat-inducing formula of sprints, incline runs and strength training. Expect to burn 800-1,000 calories per class and change your body faster than any other type of training. You’ll leave exhausted, but it’s addictive – you have been warned.

Keen runners flock to Equinox’s Precision Running class, a technical offering that challenges users to test their pacing with incline runs and timed sprints. State of the art treadmills minimise the impact on joints, reducing the chance of injury. This class is ideal for those training for a race or cardio enthusiasts looking to boost endurance.

Trainers at KXU – the pay-as-you-train version of members’ club KX – are some of the best in town and their classes second-to-none. HIIT & Run does exactly what it says; the 45-minute sessions are a killer combination of treadmill speed work and heart-raising HIIT exercises using kettlebells, dumbbells and bodyweight.

Only the brave need apply to Sweat IT’s sessions, which vary daily, building strength in the legs, glutes, arms and abs as well as speed via the treadmill. Constantly switching between the two is a sure-fire combination to boost fitness and endurance. Whether you’re looking to sculpt your biceps or smash a 5k PB, Sweat IT delivers.

Frame’s studios are renowned for their positive, upbeat vibe and their cult Cardio class is a guaranteed endorphin booster. Uplifting soundtracks and motivating instructors will see you through 45-minutes of sprint intervals and floor-based training. Re-fuel at the in-house café post class, which serves up protein bowls and antioxidant smoothies.

If you don’t work or live near a Barry’s, 1Rebel’s Reshape is the next best thing. Whether you’re a runner, spinner or HIIT fan, this class will shake up a workout rut and push fitness to the next level. With sessions focusing on the upper and lower body as well as abs, no muscle will be left untoned.

Built on three pillars – run, condition and move – Digme’s recently launched Matrix class ensures boredom isn’t an option. Using SkillMills, a curved treadmill powered by your legs, and TRX equipment driven by your bodyweight, expect to hone running technique and build strength in one fell swoop.

Despite being a stone’s throw from Bank tube, classes at the Altitude Centre take place at a simulated altitude of 2,700m. Priming your muscles to run on reduced oxygen levels will supercharge fitness levels, making this treadmill-led class the ultimate challenge for adventure seekers.
