The Corebar

Is a weighted, bent bar that is ergonomically made for the body and the exercises it is used for.

The Corebars are available in 1kg (2,2 lbs.) and 2 kg (4,4 lbs.).

Norwegian Training Concept

This training-concept is based on intervals and inspired by other popular forms of training, such as Pilates, yoga, marshal arts and dance.

Corebar focuses mainly on the core muscles, but also on "total body activation" throughout a Corebar Workout

This makes The Corebar Training Consept an intense, efficient and fun workout that gives great results, fast!

Coretube is a streaming platform where you can stream exercise videoes from the Corebar Concept at the comfort of your own home.

Workout WHERE, WHAT and WHEN you want!

Only $16.99 recurring each month. Instant access!

Long story - Short

The concept was developed by the Norwegian Anita Tonne in 2006. She is a group training instructor and personal trainer.

Februrary 2020 was the concept taken over by Mona N. Kristoffersen and is operated together with marketing leader Glenn B. Kristoffersen.

In March they saw the need for further development of the concept and they created Coretube!

Through the Webstore you can also buy your own Corebar for the ultimate experience!

Coretube has alread been filled up with a lot of different videoes with the help of Mona's master trainers and herself through 4 relases.

They have also developed the concept QuickFix for those in a hurry! These are effective 10-minutes programs for the ultimate experience when you're in a hurry!
