Experienced sports trainers know two things: All athletic motions and movements start from the core and 2) athletes who can perform near max capacity towards the end of the match has a much higher chance to win. In both cases, CrossFit as a strength and conditioning program is king thanks to its emphasis on generating force from core to extremities and its ability to dramatically increase work capacity in ways that are transferrable to all other sports.
CrossFit is basically a commitment to living an active lifestyle. The activities required to be successful at CrossFit – eating healthy, training consistently, and practicing active recovery – are (unsurprisingly) the same habits proven to improve overall health indicators such as heart rate, blood pressure, cardiovascular capacity, bone density, etc. It’s everything a person needs to achieve a happier healthier life.
