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.

INGREDIENTS

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
