This book features a series of muscle-developing workouts/exercises for entrepreneurial leaders and their teams wanting to develop fitness, strength, endurance, agility, leanness, flexibility, suppleness, and the ability to cope with adversity and to be resilient - a series of vital requirement in the process of adapting to "the new normal" demanded by our fast-changing world. In particular, these workouts are designed to enable entrepreneurial leaders and their teams to scale up transitional business ideas and innovative business concepts from the start-up phase to long-term sustainability. This muscle-power is also needed by organisations that are having to revisit or rework their established business models to adapt to the extreme volatility that is currently reshaping the business landscape. Based on Martin Tynan's doctoral thesis, adapted from his leadership change and evolution model and including the consulting experience and MBA teaching background of best-selling leadership author Stephanie Jones, the authors show how to build muscle to achieve business growth and how to sustain that growth not just for you but for your team.
