Personal Training In Small Groups

Affordable PT

When you exercise with a group, you share the cost of the personal trainer. This means you still get the help and support you need, just like in a one-on-one session, without breaking a arm and a leg for a personal trainer.

Small groups

Gyming with friends at CoreOne is lots of fun and it keeps you motivated. Our personal trainers pay attention to everyone, even in small groups. They help you do exercises each correctly and at your own pace.

Monthly tracking

Ultrasound scans every month are much more accurate than a bathroom scale. You can see exactly how much fat you lose and muscle you gain. This way, you see results and know what really works for you.
