The classes are being offered by the chain Gymbox at eight of its venues and were brought in as part of its aim to launch four to five new classes every quarter.

The chain said it noticed the use of CBD oil was becoming a trend and thought it would lend itself well to deep stretching or rehabilitation classes, The Independent reports.

Gymbox group fitness manager Hannah Curtis Well says: “This combined with the stretches and mobility exercises helps to relieve aches and pains that most desk workers experience as well as relieving stiffness from a frequent exercise.

“Cannabliss has become one of our most popular classes since its launch. It fills up within minutes of booking being open. The Cannabliss class is perfect for those sat at a desk all day looking to relieve those niggly aches and pains or for those who spend a lot of time in the gym.”

According to Gretta Philps, of CBD vendor CannaKinetic, yoga and cannabis oil are harmonious because they “amplify each other’s restorative gifts”.“CBD-infused yoga brings a heightened awareness and focus to the body helping you to sync mind, body and breath more efficiently which in turn aids with anxiety, depression and pain management,” Philps told The Times newspaper.
