Two formats
The energy of a group, the eye of a coach.
People choose a trainer for two reasons: a fixed moment that keeps them going, and help with their technique. Both formats are built on that.
Group classes with Eva
Group classes
Eva builds a varied program for every class: strength, muscle and conditioning. You train in circuits, often in pairs, while Eva helps with your technique and challenges you to get more out of it.
