If you made a list of muscle groups and asked bodybuilders to rank them based upon their training intensity, what do you think their answers would reveal? Very likely, if they were completely honest, arms and chest would rank near the very top. Abdominals would be up there too, as everyone digs a sexy six pack. As the list descended, you’d see muscle groups like shoulders, quadriceps, lats, traps, forearms, and calves. Then, most likely at the absolute bottom of this list, you’d probably find hamstrings. Ah yes, hamstrings – the muscle group we rarely see and even more rarely train. Hamstrings aren’t a wildly popular muscle group, even among bodybuilders who are judged upon complete development. Bodybuilders tend to toss in a few sets of leg curls at the conclusion of their quadriceps training day, and then move right on to the ever-showing calves. As a result, most bodybuilders have sub-par hamstrings.
