aerobic

Exercise performed while huffing and puffing enough oxygen to keep your cells happy, as opposed to those masochistic anaerobic sprints that leave you gasping like a landed fish. The magic happens when your heart rate elevates but you can still theoretically hold a conversation (though you probably won't want to). Basically, it's the difference between a pleasant jog and running from a bear.

practice

The systematic repetition of an activity designed to transform you from terrible to merely mediocre, and with enough dedication, occasionally competent. In sports and fitness, it's the unglamorous 99% of the journey that nobody posts on social media, consisting of doing the same movements until muscle memory takes over. The secret sauce that separates people who talk about their goals from people who achieve them.

drills

Repetitive practice exercises designed to bore a skill into your muscle memory through sheer monotonous repetition. Whether you're in the military, on a sports team, or preparing for emergencies, drills are the universal language of 'do this boring thing over and over until you can do it in your sleep.' Athletes particularly love complaining about them while secretly knowing they're the reason they don't trip over their own feet during competition.
