XCore Leiden


XCore Leiden

XCore at the USC

The XCORE (Extreme Core) workout is an ultimate core (the back, abdominal and hip muscles) workout using the XCO shaker, a red tube that contains a moving mass of granules.

At the beginning and at the end of every movement, the XCO shaker provides extra stress to the muscles and connective tissue throughout the body. This special effect is known as "Reactive Impact" and offers you the best training for your core.

The four different sizes of the XCO shaker ensure that both beginners and real XCORE addicts are challenged.

Are normal crunches nothing for you?

With XCORE you will train your abs in a completely different way.

XCORE ensures a strong lower back, reduces susceptibility to injuries, improves coordination and overall balance and improves your core stability, which you also benefit from in other sports.

Train your endurance, strengthen your muscles and connective tissue and burn calories. The 45-minute HIT (High Intensity Interval) workout is an energetic, simple, dynamic and intense core workout.

The music makes the difference: the mix of the latest and best hits makes you want to give everything during the explosive exercises.
