It starts gradually. First, climbing stairs becomes difficult, then shopping feels heavier than before. But what many dismiss as normal aging is an alarming warning sign: muscle loss – the invisible health crisis of the baby boomers. Sarcopenia affects everyone over 40 – and yet hardly anyone talks about it. The result? Typical age-related diseases such as osteoporosis or diabetes. Professor Dr. Jürgen Gießing, sports scientist and the leading expert on high-intensity training (HIT) in Germany, Austria, and Switzerland, has proven that age-related muscle loss can be stopped – or even reversed – with just three targeted measures.

This book provides the radically simple plan against this silent health killer.
