Helle wanted to make it clear that exercising is about getting stronger, building leaner muscles, strengthening the core, interacting socially, and living a healthier and happier lifestyle. Helle spent a number of years working at renowned gyms across London, learning and gaining experience, before opening her first studio in Holland Park in 2014. Helle has personally designed the GymClass workout to deliver distinct results in building fitness faster, sculpting leaner muscles, melting stubborn fat and strengthening the core.
