Functional fitness training refers to movements that assist with either common daily activities, work or a specific sport. While using various muscles in the upper and lower body at the same time, functional fitness training also emphasizes on core strength and stability.


We offer personalised one on one training sessions, small group classes, as well as Skype training sessions. Our exclusive training sessions are by appointment only.
