The Foundry

Strongman, one of the toughest workouts in town, uses kit seen on the World’s Strongest Man circuit. Sweat is a bootcamp session proven to torch fat and supercharge metabolism. Semi-private sessions, with a maximum of four people, are also available and a great way to refine technique.

INSIDER TIP: Towels are provided free of charge, but bring your own products if you want to shower. You’ll also need a padlock for the lockers.

The Fore

Fans of TRX – the resistance workout developed by Navy Seals – should head to The Fore, a stone’s throw from Granary Square. Classes are small, bridging the gap between personal training and group exercise, and the workout is guaranteed to get your heart racing. With an emphasis on training smarter and more efficiently, expect sprints on the SkillMill, suspended TRX planks, lunges and single-leg squats, and shoulder-strengthening moves with the Rip Trainer. Refuel post-workout with an adaptogen-spiked protein shake at The Fore’s smoothie bar before doing it all again. This class is seriously tough, but the endorphin kick will leave you wanting more.
