How long does pre-workout last?


What’s in the pre-workout?

Everyone should have experienced it. After a day’s work, I arrived at the gym exhausted. But I’m not motivated at all. Simple techniques such as changing into training gear before leaving the office, gathering training companions, and always remembering why you started are encouraging your workout. When it comes to nutrition, a healthy and balanced diet that includes proper hydration is the basis of a successful workout. Pre-workout supplements are built on this approach to support your workout needs and increase your workout potential. What are the important ingredients to check with pre-workout supplements? How do they help you reach your training and fitness goals? And How long does pre-workout last?

How long does pre-workout last?

Pre-workouts are designed to enhance your physical and mental strength and energy while workouting. These pre-workouts are taken by both athletes and gym-goers. They remain almost from thirty minutes to 1.5 or 2 hours after you take them.


The main benefits of caffeine are its effects on the central nervous system and the resulting reduction in subjective effort and fatigue (you can “feel” exercise easier). Caffeine also enhances alertness and concentration, allowing you to stay focused during your workout.

The performance benefits of caffeine are available at low doses of 1-2 mg per kilogram of body weight. For a body weight of 80 kg, a dose of 80-160 mg will support performance. However, everyone has a certain tolerance to caffeine, depending on their daily intake. Some gym-goers need higher amount of regular doses. That’s why Optimum Nutrition offers a variety of options to suit your personal caffeine needs.

Optimum Nutrition contains caffeine of175 mg per serving. This is more than double the amount of caffeine in instant coffee, which contains about 75 mg of caffeine. This pre-workout is designed for those who need more caffeine. Optimum Nutrition Amino Energy, on the other hand, contains 100 mg of caffeine per serving. Amino Energy’s caffeine comes from natural sources such as green tea and green coffee extracts.

CreatineIs responsible for producing fast, immediate energy for the muscles, causing them to contract rapidly. Creatine (especially creatine hydrate) plays a role in the production of ATP, the energy currency of muscles. Creatine helps regenerate new ATP in the muscle for immediate energy. Continuous intake of creatine at a dose of 3g per day can help generate more energy and increase the intensity of your training session. The higher the intensity of training, the greater the adaptation (faster, larger, stronger). Creatine improves physical performance, especially when you are doing strenuous exercise in the gym or on the pitch / track for a short period of time. Supplements are the most effective way to increase creatine levels in your muscles. To get the same amount of creatine from food, you have to eat a pound of meat! The Gold Standard Pre-Workout contains 3g of creatine per serving.


Beta alanine

Beta-alanine is a naturally occurring amino acid found in foods such as lean meat and fish. Beta-alanine increases a compound in muscle known as carnosine that is abundant in muscle. Carnosine is a buffer component in muscles that helps control the acidity that can often accumulate during high-intensity exercise. This acidity is caused by the high rate of carbohydrates used during high intensity exercise, which causes the production of lactic acid. It has been shown that this lowers the pH, prevents muscle contraction during exercise, and ultimately increases the incidence of fatigue. Carnosine is a buffer in muscle that can remove this acidity. Therefore, increasing the carnosine content in your muscles increases the cushioning capacity of your muscles during high-intensity exercise and helps delay the onset of fatigue. Taking beta-alanine for 4-8 weeks increases muscle carnosine levels. The Gold Standard Pre-Workout provides 1.5g of beta-alanine, while Amino Energy offers a low dose of 350mg.


L-Arginine is an essential amino acid found in seafood, watermelon, nuts and meat. L-Arginine can increase the synthesis of nitric oxide (NO) in blood.

L-citrulline is a non-essential amino acid and a natural source of diet, but is produced primarily by glutamine in the small intestine. Since it is a precursor to L-arginine synthesis, it indirectly increases NO levels in the body. Studies have shown that L-citrulline supplements are more effective at increasing blood levels of L-arginine than directly supplementing the same dose of L-arginine. The Gold Standard Pre-Workout contains 750 mg of citrulline per scoop.

Another common ingredient in BCAA (branched chain amino acid) pre-workout supplements is BCAA. These amino acids are literally components of all biological proteins. All proteins in your diet and supplements are broken down into amino acids in your body to support muscle repair and recovery. The branched chain amino acids (BCAA) leucine, isoleucine, and valine are all essential amino acids. The body cannot produce them and must be taken through a diet or supplement. Amino Energy provides muscles with 5g of amino acids per serving.
