Oh "cardio", the very name itself strikes fear and loathing into many people I know and love. Cardiovascular endurance is the ability of the heart, lungs, and circulatory system to supply oxygen to working muscle tissue. It is by far and away the most critical element of overall fitness and health.
Cardiovascular endurance is the base upon which all other training is built. Basic strength is also very important but in the grand scheme of things cardio trumps strength every time. Cardio is crucial for weight management, fat loss, body composition, and recovery. It is also a critical element in almost all sport / athletic endeavors. High level athletes competing in hockey, soccer, basketball, combat sports, gymnastics, rugby, swimming, and most other sports require high levels of cardiovascular endurance.

The question remains however, why do so many people hate to do cadio? I think many people automatically conjure an image of some emaciated runner wearing a heart rate monitor and shamefully ugly "running" shorts. Many people simply hate running.....they find it painful, awkward, and humiliating.
The non-runners among us should not use this as leverage to abstain from cardio. Just the opposite, non-runners are missing out on the best overall cardiovascular workout available to mankind. A reasonable substitute needs to be located in order to promote optimal fitness and health.
Cardio should be performed a minimum of three times per week for at least 30-minutes to achieve the desired results, ie weight loss, increased energy levels, improved fitness. Cardio exercises should be large and incorporate as much muscle mass as possible. Good options include, swimming, running, eliptical machines, cross-county skiing, and stepper machines.
Bikes and rowers are decent but it is much more difficult to achieve high-intensity heart rate values on these pieces of equipment and they are generally not as effective for building and improving cardiovascular ability. Part of the reason is that these pieces are weight supported and do not require the same level of overall effort as un-supported activities.
Until next time......peace out. M
