Cardio Enthusiasts: Discover a More Effective Training Method for Fat Loss and Heart Health!
It is common to hear fitness professionals and medical doctors prescribe low to moderate intensity aerobic training (cardio) to people who are trying to prevent heart disease or lose weight. Most often, the recommendations constitute something along the lines of "perform 30-60 minutes of steady pace cardio 3-5 times per week maintaining your heart rate at a moderate level". Before you just give in to this popular belief and become the "hamster on the wheel" doing endless hours of boring cardio, I'd like you to consider some recent scientific research that indicates that steady pace endurance cardio work may not be all it's cracked up to be.
First, realize that our bodies are designed to perform physical activity in bursts of exertion followed by recovery, or stop-and-go movement instead of steady state movement. Recent research is suggesting that physical variability is one of the most important aspects to consider in your training. This tendency can be seen throughout nature as all animals demonstrate stop-and-go motion instead of steady state motion. In fact, humans are the only creatures in nature that attempt to do "endurance" type physical activities. Most competitive sports (with the exception of endurance running or cycling) are also based on stop-and-go movement or short bursts of exertion followed by recovery. To examine an example of the different effects of endurance or steady state training versus stop-and-go training, consider the physiques of marathoners versus sprinters. Most sprinters carry a physique that is very lean, muscular, and powerful looking, while the typical dedicated marathoner is more often emaciated and sickly looking. Now which would you rather resemble?
Another factor to keep in mind regarding the benefits of physical variability is the internal effect of various forms of exercise on our body. Scientists have known that excessive steady state endurance exercise (different for everyone, but sometimes defined as greater than 60 minutes per session most days of the week) increases free radical production in the body, can degenerate joints, reduces immune function, causes muscle wasting, and can cause a pro-inflammatory response in the body that can potentially lead to chronic diseases. On the other hand, highly variable cyclic training has been linked to increased anti-oxidant production in the body and an anti-inflammatory response, a more efficient nitric oxide response (which can encourage a healthy cardiovascular system), and an increased metabolic rate response (which can assist with weight loss). Furthermore, steady state endurance training only trains the heart at one specific heart rate range and doesn't train it to respond to various every day stressors. On the other hand, highly variable cyclic training teaches the heart to respond to and recover from a variety of demands making it less likely to fail when you need it. Think about it this way -- Exercise that trains your heart to rapidly increase and rapidly decrease will make your heart more capable of handling everyday stress. Stress can cause your blood pressure and heart rate to increase rapidly. Steady state jogging and other endurance training does not train your heart to be able to handle rapid changes in heart rate or blood pressure.
The important aspect of variable cyclic training that makes it superior over steady state cardio is the recovery period in between bursts of exertion. That recovery period is crucially important for the body to elicit a healthy response to an exercise stimulus. Another benefit of variable cyclic training is that it is much more interesting and has lower drop-out rates than long boring steady state cardio programs.
To summarize, some of the potential benefits of variable cyclic training compared to steady state endurance training are as follows: improved cardiovascular health, increased anti-oxidant protection, improved immune function, reduced risk for joint wear and tear, reduced muscle wasting, increased residual metabolic rate following exercise, and an increased capacity for the heart to handle life's every day stressors. There are many ways you can reap the benefits of stop-and-go or variable intensity physical training. One of the absolute most effective forms of variable intensity training to really reduce body fat and bring out serious muscular definition is performing wind sprints. Most competitive sports such as football, basketball, racquetball, tennis, hockey, etc. are naturally comprised of highly variable stop-and-go motion. In addition, weight training naturally incorporates short bursts of exertion followed by recovery periods. High intensity interval training (varying between high and low intensity intervals on any piece of cardio equipment) is yet another training method that utilizes exertion and recovery periods. For example, an interval training session on the treadmill could look something like this:
Warm-up for 3-4 minutes at a fast walk or light jog;
The take-away message from this article is to try to train your body at highly variable intensity rates for the majority of your workouts to get the most beneficial response in terms of heart health, fat loss, and muscle maintenance.

Spinning exercise or studio cycling is not only popular these days it's an excellent form of fitness. It helps strengthen your heart, tone your glutes, calves, thighs in addition to being a great exercise to slim legs.
Running for Success
Though it may not seem like it when we're drenched in sweat and our legs feel like lead, marathon running is as mental as physical. When we're exhausted, continuing consists of mind over matter. This takes enormous mental power. Once developed, this skill can be transferred from the racetrack to the boardroom.

The major benefits of cardio-boxing include:
The Best Cardio Workouts
The benefits of exercise are abundant and well documented, and the best cardio workouts can increase your quality of life. One can hardly read a magazine or watch the news without stumbling across a study or doctor claiming a new benefit from exercise.
Cardios Effect on Overall Health
When most people hear the word "Cardio", their mind automatically pictures jogging, or threadmills, or stationnary bikes. Yes, those are some forms of cardio. They also think it's only purpose is to loose fat. But doing cardio has many benefits.
Winter Running: Survival Tips For Your Feet
The days are shorter, the air is colder and the streets are slicker. Yet, many will still brave the cold, damp and dark streets and trails as winter sets in. For those who don't mind a little rain, snow, sleet or below freezing temperatures and run to survive the winter, it is important to know how to protect the feet so they too, can survive the winter months.
Benefits of Elliptical Training
The basic motion of an elliptical trainer is a smooth, flowing...well...elliptical motion. The low impact nature of these machines greatly reduces stress on the joints of the lower body (ankles, knees, and hips).
Benefits of Aerobic Exercise
The real benefits of aerobic exercise are achieved by increasing your heart rate and breathing hard for an extended period of time. During this aerobic activity your body produces more energy and delivers more oxygen to your muscles. Your heart beats faster and increases the blood flow to your muscles and then back to your lungs.

Elliptical workouts basically involve aerobic or cardiovascular exercise. Elliptical cross trainers can be intimidating at first glance but once you get familiar with them you will find them easy to use and a fun part of your routine.
Depending on your goals and body type, different amounts of cardio may be required. A lean "hard-gainer" trying to add mass may benefit from only one or two cardiovascular sessions per week. On the other hand, someone like myself who is extremely prone to storing fat and sensitive to carbohydrates may require 3 or more sessions in order to maintain peak physique. Since you can only get better at a particular exercise by performing it, those interested in running marathons or participating in endurance events such as a triathlon must increase their frequency of cardio in order to prepare for the event.

Nike Free does not think so; and neither should you. Read on to find out why this concerns every one of us, our health and a good deal of wasted money. This is not a story of the Nike Free shoe; it's about our freedom and growth.
Cardiovascular Training - From the Heart!
Cardiovascular training, or aerobics, requires a different approach than other body parts. At the "heart" of cardiovascular training is one basic premise: if you elevate your heart rate to 65-80 percent of your maximum and keep it there for a period of at least 12 minutes it will stimulate the production of fat-burning enzymes. It will also strengthen your heart and increase the capacity of your lungs to re-oxygenate your blood more efficiently. The idea here is not to work yourself to a frenzy and go beyond your target heart rate, but to stay within that magic training range of 65-80 percent of maximum for a minimum of 12 minutes and, optimally, for 20 to 30 minutes.
