DAREBEE Workout: What it Works
Size is not the only component of strength but, in general, bigger muscles lead to strength gains. This is where XXL Biceps comes in. A workout where form is important and speed of execution of each has to be as slow as possible in order to recruit as many muscle fibers as possible. Choose a weight that is challenging and maintain a tight core throughout by positioning your body properly to engage it.  
Extra Credit: Go as slow as you possibly can.
