Welcome to Fitness!

CrossFit is a fun and highly effective means of achieving an excellent level of fitness.
Whenever someone is trying to improve their overall fitness level, there are 10 key components that any well-rounded program should address.

  1. Cardiovascular/respiratory endurance – The ability of body systems to gather, process, and deliver oxygen.
  2. Stamina – The ability of body systems to process, deliver, store, and utilize energy.
  3. Strength – The ability of a muscular unit, or combination of muscular units, to apply force.
  4. Flexibility – The ability to maximize the range of motion at a given joint.
  5. Power – The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.
  6. Speed – The ability to minimize the time cycle of a repeated movement.
  7. Coordination – The ability to combine several distinct movement patterns into a singular distinct movement.
  8. Agility – The ability to minimize transition time from one movement pattern to another.
  9. Balance – The ability to control the placement of the body’s centre of gravity in relation to its support base.
  10. Accuracy – The ability to control movement in a given direction or at a given intensity.

In order to successfully and efficiently improve each of these 10 components to fitness, CrossFit uses large, full-body movements that are very natural to human movement. This makes the exercises used natural and safe, which is obviously ideal. Another key to developing good overall fitness is to engage in exercises and activities that vary in intensity (how hard you work), and duration (how long you work). This allows the body to get stronger and adapt to a wide variety of stimuli.

Basically, the ideal fitness program would give you the best ability to engage in, and succeed at the largest number of possible athletic endeavours.
