Urban Life Health Centre is an extensive venue for (Hot) Yoga and Vitality. They offer classes to help you improve your "Preventive Healthy Lifestyle". Whether this is through their (infrared) Hot Yoga or Warm Pilates classes, or through the different authentic yogastyles they offer (such as Ashtanga, Hatha and Yin Yoga). The classes aren't just a good workout in which you'll work on strength, balance and stamina, but they're also a chance to improve your consciousness through mindfulness and meditation. After class you can enjoy the complimentary Yogi-tea, mint water and small healthy snacks. Multitasking doesn't get more relaxing than this!
Please be on location 15 minutes before the class (especially if it's your first time). Dress in light clothes; even during non-Hot classes it's nice and warm at Urban Life Health Centre. Bring a large (beach)towel. Yoga materials (mats and props) can be used without extra charge at the location. Make sure to hydrate sufficiently, especially before taking a Hot Yoga class.
And get access to 155 gyms and studios in The Hague with one sports membership.
