is the easiest way there is to jump-start your fitness, develop positive lifestyle habits and increase your base fitness level without training for hours each day. Using well-established scientific principles on micro-workouts, month-long challenges help you transform your body and enhance your brain in the comfort of your own home.

With over eight years' worth of collective exercises the 100 Darebee Fitness Challenges, A4-sized mega-collection guarantees you will have something active to do every day of the month.

This is a great way to:

• Energize yourself each day
• De-stress at the end of the day
• Develop mental focus and discipline
• Raise your fitness base line and level up
• Create an incremental plan to better health
• Build up your physical and mental resources
• Maintain your fitness level during training lay-offs
• Develop new habits that help your physical and mental health
• Incrementally become a better version of yourself, one day at a time

Each of the 100 month-long challenges comes with a handy grid that tells you what to do each day. Once you do it you cross it out keeping visible track of your daily progress. This also helps you stay focused and motivated each day.

Once you complete one monthly challenge you can pick another. You can choose to do each one sequentially or you can dip in from any part of the book that catches your fancy. The 100 Darebee Fitness Challenges contains a good mix of physical and mental challenges you can undertake each month, helping you transform yourself both inside and out.

Field-tested with volunteer groups across the globe, Darebee's 100 Fitness Challenges will be a constant companion on your fitness journey for years to come.
