NO BULL XMT Pre-Workout Formula enhances muscle force, velocity and endurance allowing you to lift heavier weights for more reps. The end result is Bigger, Stronger Muscles and Better Workouts! NO BULL XMT (Extreme Muscle Tension) has been formulated with clinically researched ingredients to enhance workout performance and muscle growth through a proven training concept called "Time Under Tension." During a resistance weight training workout, the amount of time your muscles work is measured in repetitions and the amount of tension is measured in weight. Increasing the numbers of reps (time) and the amount of weight on the bar (tension) during a set increases the workload placed on your muscles and stimulates maximum muscle growth. NO BULL XMT is formulated to do just that - More Reps + More Weight= More Muscle Growth. In the development of NO BULL XMT, MuscleMeds researchers focused on a key mechanism in muscle coined "Excitation-Contraction." Enhancing this mechanism of action in muscle tissue helps increase muscle force, velocity and endurance thereby increasing "Time Under Tension" and total workout performance. In addition to enhancing muscle "Excitation-Contraction," NO BULL XMT"s advanced synergistic design also increases energy, muscle pumps and anabolic signaling, making it the ultimate performance enhancing pre-workout formula. NO BULL XMT is the Pre-Workout Formula for those who want more. More Reps + More Weight = More Muscle Growth!
