While there are many different schools of thought on what Frequency Nike Air Force 1 Flyknit Low All White On Clearance , Intensity, Time and Type of Cardio is the ultimate best for fat burning, Pittsburgh Personal Trainer Scott Hayward has broken down each type of intensity for cardio and has outlined both some benefits and risks that are inherent with each.


Fasted cardio in the morning


One of the most controversial fat loss techniques is performing cardio first thing in the morning on an empty stomach. This method is widely embraced by bodybuilders and recommended by many Personal Trainers and nutritionists. Other experts claim that the risk of muscle loss is too high and they argue whether workout timing makes any difference in the overall scheme of 24 hour energy expenditure. With low blood sugar and low glycogen levels on awakening, it appears that the body is in a perfect state to burn fat preferentially, but combined with high a.m. cortisol levels, it may also be a perfect state to burn muscle. Therefore Nike Air Force 1 Flyknit Low Red For Sale , the benefit is high, but so is the risk. Body composition must be carefully monitored when using this technique.

BENEFIT: 3 (high)


Cardio in the morning after protein consumption


One of the biggest concerns brought up by opponents of fasted morning cardio is the potential for losing lean body mass. One way to help combat the possible loss of lean body mass is to eat a small protein-only meal or to consume a protein drink (no carbs) immediately upon awakening, then perform the cardio shortly thereafter. This decreases the risk by suppressing cortisol and preventing muscle breakdown, while maintaining the high benefit by keeping your blood sugar and insulin levels low.


RISK: 2 (moderate)
BENEFIT: 3 (high)


Cardio at night


Many bodybuilders and Weight Loss seekers perform cardio late at night and then do not eat afterward in an attempt to increase fat loss. There are benefits to this method, but they are moderate at best, and the risks are high. Late night training may also keep you awake Nike Air Force 1 Flyknit Low Black Outlet , disrupting your sleep cycle and recovery. Once you do fall asleep, your metabolic rate decreases rapidly, so you don’t reap the full value of the post workout metabolic increase that is achieved with exercise earlier in the day. Risk of muscle loss is high, so body composition must be monitored very closely.


RISK: 3 (high)
BENEFIT: 2 (moderate)


Short duration, high intensity interval training


One of the most popular trends in fitness today is high intensity interval training (HIIT). These workouts consist of short periods of high intensity work intervals followed by short periods of lower intensity recovery intervals. Generally, the intervals are 30 to 120 seconds in length and the total duration is in the 15-25 minute range. Research has shown that H.I.I.T Training causes a larger increase in post-exercise energy expenditure than moderate intensity Discount Men's Nike Air Force 1 Low 07 White Gold , steady-state exercise, which keeps you burning calories at an elevated rate for an extended period even after the workout is over. There are risks, especially to the beginner, the deconditioned or the person unaware of his or her health status. However, because intensity is relative to each individual, risk is moderate and easily managed Men's Nike Air Force 1 Low CNY Fireworks White Cheap , while the benefits are high. For someone who is already highly fit, the risks are lower.
