Being involved in the military might include stress levels that are
far beyond the recommended daily allowance. Then again, it might involve
only typing or vehicle maintenance. One thing is for sure, most
military careers involve doing the push up. Perhaps the most fundamental
of all bodyweight drills, the push up not only involves strengthening
and localized endurance of the chest, shoulders, and arms, but also the
bracing of the torso. This bracing or stability is often referred to
these days as core strength. I tend to think that we want to avoid
comparisons to aerobics bunnies and harpy-like reality show trainers, so
we will avoid the word: core. Let us instead focus on bracing and
stability and its primary drill: the plank.
