Acid Training

Acid Training is a Nordic fitness concept located at Tegnérgatan 18 in Vasastan, Stockholm. The studio offers high-intensity group training sessions of 54 minutes that combine cardiovascular and strength training in a structured environment. Each participant receives a heart rate monitor upon arrival and can follow their heart rate in real time via screens displaying the five heart rate zones used in the training. The method is based on the EPOC principle, meaning the body continues to burn calories even after the session has ended.

The training is led by coaches who help members set individual goals, whether the aim is weight loss, increased strength or improved fitness. In addition to the regular classes, periodic challenges are offered, including a four-week course in bootcamp format and a half marathon organised by the studio. There is also the option to book a massage directly through the studio's website.

Membership is taken out on a rolling basis with no fixed-term commitment and is available in two variants depending on how frequently one wishes to train. A class pass is also available for those who prefer flexibility without a fixed monthly fee. The booking system is managed digitally and classes can be booked up to two weeks in advance.
