The Les Mills Core class can be tackled in just 30 minutes, we would recommend attending two or three classes each week for maximum core toning results.
If you're trying to lose weight whilst toning your core, include some cardio and strength training before or after your Core class to help blast calories and burn fat.
After the Les Mills Core class, leave 24 hours before doing more resistance training to allow your body some recovery time. This is where a cardio session in the gym will work well.
