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.
