You may think HX5 looks extreme but all movements are universally scalable therefore if you cannot do something there are similar alternative that can substitute that movement until you have developed the skill / technique or improved strength to achieve this.
HX5 is for everyone who wants to work hard and achieve something, whether this is sports performance, working in difficult environments (Military, Police, Fire, Paramedic) or you just want to increase your general fitness. Along with HX5 training of course your body composition will change, losing fat and building muscle will just come with the territory.
If body composition is at the top of your list of priorities, HX5 will work. As humans we "adapt," therefore we need to create an uncomfortable environment for your body to "adapt" too. With HX5 varied program it is hard for your body to adapt to a set stimulus therefore you will always be progressing and challenging yourself.
