Whatever life-style people say about ‘wellness’, ‘fitness’ and so on – what they really mean is your personal appearance: the externals, so speak. Less well-known, less fashionable – and far more important – are the ‘segmental’ muscles, as they’re called: the bands of muscles that surround the skeleton and make sure that we can stand up straight, sit down properly and maintain balance. It’s these muscles that get lazy, and which are particularly badly affected by desk-work. Our patented German-made swing stick is the answer. Once set in motion (see instructions for use), the oscillations produce a pleasing dynamic of their own – the user is obliged to keep up the oscillating movement and to counter it with the segmental muscles we’ve just described. It’s fun to use, does wonders for your posture – and it’s hardly surprising that professional physiotherapists swear by it.
