A: Not at all.

The program requires you to have only light weights of 0.5-3kg, which you can use any domestic object for, such as a piece of vegetable or fruit or a bottle of water. You'll also need a light piece of rubber band in very few of the program's videos. Otherwise, you'll need only a chair and a yoga mat, which I assume you are most likely to have anyway.

A: 1. This course is based on the clinical field of muscle testing and the practice of diagnosing and treating sports injuries accurately.
You receive a complete list of specific exercises used to treat the most vulnerable locations and structures of your entire movement system. You'll systematically exercise (in advance!) human body weaknesses that I as a physiotherapist would look for.
2. To my knowledge, nowhere even before the responsible elements responsible for human body physical injuries gathered for self-exercise and maintained safely the potentially injured the individual.

Finally, let me reassure you that any piece of information or applicable maneuver in the The Durable Body Method™ program is used by me and constantly evolving, on a daily basis and throughout my entire career. 

I didn't invent the building blocks of this content. It is hugely based on common and well-known sources and superb practitioners, from whom I was lucky enough to learn.

All I did here is to gather, organize, present, and deliver the information to you - in the right forms and order, as an interactive program for preventing injuries over your entire body.  

A: This is just like brushing your teeth and flossing them. You can stop but your teeth will eventually deteriorate and decay.

Same with your muscular system. As we're aging, we're gradually losing our general muscle mass and our ability to work in an optimal balance, control, and coordination, An injury will be the byproduct of these and it's in our hands to prevent it.
