Bena is made up of several major Alpha Primal XL muscle groups. Gluteus = three muscles, quadriceps = 4 muscles, hamstring = 3 muscles. Then we have not even mentioned all synergists and stabilizers. To achieve growth in all parts, both hard and smart training is required. A couple of exercises a week do not last. Alpha Primal XL scientific basis for selecting exercises that qualify for this list is about EMG activation. http://healthpurelives.com/alpha-primal-xl/
