The answer is always the same no matter what comes next.
The specificity principle is a fancy way of referring to the simple fact that you get better at the specific tasks that you consistently practice. Whether it’s handstands or pistol squats or running, to improve your skills on anything, I recommend the direct approach.
For athletes, this means that much of their training time must be devoted to their specific discipline. The little bit of supplemental training they do usually consists of things like squats and cleans to maximize their strength and explosive power. After all, the combination of skill and strength is what leads to success in most sports.
For the rest of us, however, the specificity principle means that once we can establish a baseline of strength through basic exercises like squats, pull-ups, push-ups, etc, we can elect to devote our workout time towards whatever we like.
While skill enhancement isn’t the best means towards weight loss, finding new challenges helps keep your workouts fresh while allowing you to build up a skill set that can make you stronger and more functionally fit across different modalities.
The goals themselves aren’t really important, but working towards something specific might help you stay focused. After all, goals are just a fantasy; the training that you do today is real.
