Recently, someone in the gym asked us about an exercise we were performing, specifically inquiring if it was targeting our abs and then questioning how it differs from the abdominal crunch machine he was using. We explained that this particular variation of the abdominal crunch would activate more muscles in his core, since the weight could force his body left or right as well.
When he showed obvious frustration and explained how he’d been using the machine for years with no progress, we asked how he was using the machine, specifically referring to how many reps and sets he was doing. When he told us that he performed 30-40 reps per set, we asked him if he was happy with his upper arms. When he said that he was indeed happy with that body part, we asked him how he trained his arms, specifically referring to how many reps and sets he was doing. When he told us that he performed 8-12 reps per set, we presented the question: why are you training your abs differently?
