ONYX Health Club 24/7's Core & Booty Group Class has been created for participants who would like to sculpt their core & booty into amazing shape. It is also designed to provide a total-body workout and focused on key muscle groups.

ONYX's Core and Booty program also focuses on the cardiovascular and strength aspect of fitness. The overall goal is to burn calories, reduce excess body weight, improve cardiovascular endurance and increase lean muscle mass. Several of the exercises require you to maintain a specific posture, conditioning the core muscles of the body while other muscle groups are being exercised. You will be lead throughout the entire duration by a professional ONYX group class instructor who will ensure that you are staying in form.

Performing squats primarily focuses on the booty and legs. Core & booty group class is a solid full-body workout. ONYX group classes create efficient use of your time and help you maximize your gains. This allows you to complete an exercise routine that will promote effective weight loss, improved cardiovascular endurance, increased lean muscle tissue and improved coordination and balance.

There are many other benefits of our Core & Booty Group Class, which includes the improvement of your overall mental health. It has long been known that consistent aerobic exercise can help reduce high blood pressure, hypertension, stress and even depression-related symptoms. Working out (especially in the Core & Booty Group Class) will release tons of endorphins, which will increase your mood.
