This experimental training system is harder than H-E-double-toothpicks, so give it a shot: the all-new 666 Training is tempting... Join Marc and Derek for some more intense biceps training in episode #3!
In this third episode, the dudes over at Scivation come back and blast their biceps with some more high-volume, short rest period training using standing bicep cable curls for 6 sets of 6 reps in 6 minutes flat! Feel the burn on that last set, baby!
