Former recruitment consultant Helen Smith, 35, led the first circuits-style workout class for ten participants on Saturday evening in Southampton.
The hour-long class, which was attended by people aged between 33 and 70, included jumping-jacks, sit-ups, push-ups and partner work.
It has been described as ‘gentle boot-camp style exercise with partner games and teamwork’ suitable for all fitness levels.
‘You also don’t have to think about washing sweaty gym clothes after the class, and it’s a great way to celebrate the body.’
While the class is a nude activity, women can wear sports bras for comfort and participants can wear trainers for some exercises if they wish.
