Depending on the duration and intensity, cardiovascular exercise can deplete muscle glycogen levels significantly. Supplementing with Xtend will assist in sparing muscle glycogen and muscle tissue and increase gluconeogensis. In addition to this, the citrulline-malate in Xtend will increase your performance due to its ATP boosting effects. If you are only doing cardio on a given day, I would treat this just as you would a weight training workout.
Start sipping your Xtend 15 minutes prior to the start of your cardio i. Continue sipping Xtend throughout your cardio session. Dosing will depend mainly on the duration. I would suggest taking 1 serving of Xtend per 10 minutes of cardio. Another option would be to decrease the amount of Xtend and add some whey protein for session greater than 40 minutes. For example, you could do 3 servings of Xtend and 1 serving of Substance WPI with the matching flavor. If you perform cardio after your weight training session, I would recommend increasing your Xtend servings from 3 to servings.
Add all of the servings to a jug or water bottle and sip throughout your weight training session as usual. Whatever Xtend you did not drink during your workout is to be consumed during your cardio session. HIIT is an anaerobic form of cardio. While a HIIT session is usually shorter in duration then a cardiovascular session, it is much more intense.
I would recommend using servings of Xtend during the session. The main energy-consuming process in the cell is protein synthesis. MTOR activation is vital for skeletal muscle hypertrophy. Interestingly, mTOR is also a nutrient sensor of amino acid availability, specifically of leucine availability. Our goal is to keep ATP levels elevated while working out. To do so, we must supply the needed nutrients and substrates before and after the workout to keep ATP levels elevated and our bodies primed for growth.
Breaking of the two outer bonds results in the release of energy. When the most outer bond is broken, the energy is released and ADP and Pi are left behind. Creatine, which is bonded to a phosphate ion, transfers energy to the ADP and Pi molecule by breaking its own bond.
This regenerates the ATP molecule, which means one now has more energy to use. Skeletal muscle has a limited storage of creatine. Therefore supplementing with creatine increases your ability to form ATP and therefore increases the available energy for exercise Casey et al.
More importantly to our topic on hand, by keeping ATP levels by supplementing with creatine we increase protein synthesis through mTOR activation. One of the principles that have helped Sadik do this is the consistent consumption of th Protein provides essential amino acid building blocks for the development of new muscle tissue, it can help preserve mu Hydration Mouthwatering Hydration Hydration is a buzzed about issue—after all, it's very common to hear and read the advice, "stay hydrated"—but we don't talk as much about the underlying pieces of hydration: What hydration means, why it's important to everyone and especially athletes!

Of the nine essential amino acids, three are the branched-chain amino acids BCAAs : leucine, isoleucine and valine. They are also a popular dietary supplement sold primarily in powder form.
The BCAA leucine activates a certain pathway in the body that stimulates muscle protein synthesis, which is the process of making muscle 1 , 2. In one study, people who consumed a drink with 5. Summary BCAAs play an important role in building muscle. However, your muscles require all the essential amino acids for the best results. This soreness is called delayed onset muscle soreness DOMS , which develops 12 to 24 hours after exercise and can last up to 72 hours 8.
Several studies show that BCAAs decrease protein breakdown during exercise and decrease levels of creatine kinase, which is an indicator of muscle damage 11 , 12 , Therefore, supplementing with BCAAs, especially before exercise, may speed up recovery time 15 , Summary Supplementing with BCAAs may decrease muscle soreness by reducing damage in exercised muscles.
Just as BCAAs may help decrease muscle soreness from exercise, they may also help reduce exercise-induced fatigue. Everyone experiences fatigue and exhaustion from exercise at some point. How quickly you tire depends on several factors, including exercise intensity and duration, environmental conditions and your nutrition and fitness level Your muscles use BCAAs during exercise, causing levels in your blood to decrease.
When blood levels of BCAAs decline, levels of the essential amino acid tryptophan in your brain increase In your brain, tryptophan is converted to serotonin, a brain chemical that is thought to contribute to the development of fatigue during exercise 19 , 20 , In two studies, participants who supplemented with BCAAs improved their mental focus during exercise, which is thought to result from the fatigue-reducing effect of BCAAs 22 , However, this decrease in fatigue is unlikely to translate to improvements in exercise performance 24 , Summary BCAAs may be useful in decreasing exercise-induced fatigue, but they are unlikely to improve exercise performance.
Muscle proteins are constantly broken down and rebuilt synthesized. The balance between muscle protein breakdown and synthesis determines the amount of protein in muscle Muscle wasting is a sign of malnutrition and occurs with chronic infections, cancer, periods of fasting and as a natural part of the aging process Several studies support the use of BCAA supplements for inhibiting muscle protein breakdown.
This may improve health outcomes and quality of living in certain populations, such as the elderly and those with wasting diseases like cancer 29 , 30 , Summary Taking BCAA supplements can prevent the breakdown of protein in certain populations with muscle wasting.
