I was reading Stephen Barr's Modern Physics and Ancient Faith last week and on page 78, amidst a discussion of symmetry and design, Barr mentions that the most compact way to stack marbles in a box, as an example of order, is known as a "hexagonal closest stacking" (hcp) [link]. His point is that the order of the hcp matrix is a result of the deeper symmetry of the (designed) symmetry of the spheres themselves.

This illustration, in turn, reminded me of a mathematical puzzle I read about years ago, perhaps in Amir Aczel's Fermat's Last Theorem, about a proof for the most optimized arrangement of objects inside a container (though I'm probably misremembering it). By the end of last night's workout, I realized an application of hcp-ordering in my fitness life: I'm going to need to "optimize" my training at Planet Fitness or I'm going to outgrow it within weeks.

Last night, while squatting, I started to feel my old instinct and capacity for strength return, and I knew it's only a matter of time before I regain enough strength to start training with very heavy weights. This will, in turn, put me in risk of setting off the infamous "Lunk Alarm" at Planet Fitness. That is a bridge I will cross when I must.

Even apart from heavy squatting and big lifts that would entail dread sounds of exertion in the trademarked "no judgment zone" that is Planet Fitness, I realized that I'll need to make the most of the impressive array of cable machines there. There are no free barbells and the fixed-weight barbells only go up to 60 lbs. This is fortuitous in its own right, since it will force me to train my way to the heaviest available dumbbells (80#?), which is a practice I endorse anyway.

I foresee using pre-exhaustion, unilateral, thick-grip, drop sets, and high-intensity methods to "stack" as much training capacity into Planet Fitness as possible. Stay tuned...
