UNLEASH THE POWER OF LEG DAY
LEG DAY isn’t formulated to move some weight. It is formulated to help you move some HEAVY ASS WEIGHT.
We’re talking the kind where the bar is bending. The kind where everyone around you stops to watch in amazement. It’s at that moment where those who are about to witness greatness respect the drive and heart you have. It’s where respect is earned by both those around you as well as the weights.
You’re not here to play. Those weights would break mere mortals – BUT NOT YOU. Not today. Not ever. NutraBio LEG DAY has just raised the bar… so you can too.
WHY CHOOSE LEG DAY?
FUEL THE MOST GRUELING WORKOUTS
LEG DAY is a special edition of our top-selling intra-workout supplement, Intra Blast. LEG DAY takes Intra Blast to new heights and beefs it up to further improve your workout performance for those killer workouts where you leave everything in the gym. Those workouts where you question if you even want to attempt walking out to your car. In those workouts, you don’t want to hit the wall, you don’t want to throw in the towel, you want to annihilate your muscles and force new growth. NutraBio LEG DAY can help you do just that.
Best of all, LEG DAY is stimulant-free, allowing you to stack LEG DAY with your favorite pre-workout to maximize your results.
MUSCLE GROWTH & RECOVERY
When looking at muscle growth and recovery, the main contributor comes in the form of amino acids. In order for broken-down muscle fibers to properly rebuild and repair, amino acids need to be present. NutraBio LEG DAY not only provides your muscles with the highest quality BCAAs in the scientifically studied 2:1:1 ratio, but it also includes ALL of the essential amino acids (EAAs).
Research has shown that muscle growth and recovery are more significant when all nine essential amino acids are present versus what many profiles out there utilize, which are just the three BCAAs.
NutraBio LEG DAY utilizes a clinically dosed formula, which includes HPLC-quality amino acids and BCAAs that are naturally fermented. This high-powered amino acid matrix helps promote and preserve lean muscle tissue, aids in recovery, reduces muscular fatigue during training, and minimizes post-training soreness (delayed-onset muscle soreness or DOMS).
STRENGTH & PEFORMANCE
The strength and performance matrix found in NutraBio LEG DAY consists of ingredients that, when combined, help provide you with unrivaled strength and performance. Let’s face it, grueling workouts demand more than a traditional blend of ingredients, you need something that works as hard as you do.
LEG DAY can help enhance your training by helping increase power output, elevate performance, metabolize fat, promote protein synthesis and proper recovery, boost nitric oxide production, and protect cells from physiological stresses produced through exercise.
Additionally, LEG DAY may promote both anabolic and anti-catabolic responses in the body to help build and preserve lean muscle tissue.
ELECTROLYTES & HYDRATION
LEG DAY helps take your hydration to the next level by including key minerals and electrolytes to replenish what was lost during your workout. Proper hydration is essential when it comes to workout performance. As little as a 2% reduction in body water can drastically reduce performance levels and hinder your results.
Every cell in your body needs water. For your muscles to function, water is required to help facilitate the electrical current that creates an impulse the muscle needs to be told to contract and relax. By managing hydration and electrolyte levels, the body is better able to transport key nutrients (such as amino acids) out to the working muscles, which can help reduce fatigue, improve endurance, and enhance recovery.
Something else to consider is that maintaining hydration can help improve protein synthesis, which is essential in building lean muscle mass. Additionally, you need adequate hydration levels to achieve the coveted pump during workouts and push fluid into the muscles. Otherwise, you risk looking flat, and your muscularity can appear drastically reduced.
