We run a busy schedule of over 80 group exercise classes every week at our studios at Harpenden Leisure Centre. These include a mixture of Aerobic, Body Conditioning and Calm classes.

You can take a look at our group exercise timetable at the bottom of this page. To book a class through the 1Life APP or online, you must first register free for a 1Life card or be a current member.

You can also book by telephone on: 01582 767722


Take time out to relax and enjoy these classes, “Life takes it out of you.... these classes give it back.” Increase your flexibility, take an hour out of your busy schedule and learn to unwind. The best way to plan your group fitness workout is to aim to do at least one of each colour within a week.

Body Conditioning

Toning, strength and endurance. These classes are designed to get your muscles working and looking great.

Introducing Les Mills Virtual


With virtual we can schedule more classes, more often, providing more variety and offering you more opportunities to workout even when an instructor is not available.

At 1Life we’re proud to offer Les Mills virtual classes, so despite there being no instructor with you in the room, you’ll know the content will be just as professional and just as fun!! 😀

Participating in a virtual class could not be more simple:

 Arrive 5 mins before the scheduled start time
 The class is pre-recorded and is set to start automatically
 You will have access to any equipment required during the class
 The instructor on the screen will guide you through the workout
 The video content is one-way, nobody can see your workout unless they’re in the room with you
 If you need any help, please ask at reception
