The last thing you want when crushing a workout is to lose focus. Not only can it cause you to lose your mind-muscle connection, but a lack of focus could break down your form and result in an injury. L-tyrosine can help increase mental performance, heighten attention, enhance focus, and improve alertness. Get and stay dialed in with your workout so that you can effectively break down the targeted muscle fibers and then flood them with the amino acids necessary to build them back bigger and stronger.
