I've been powerlifting for a little over two years now. Powerlifting is, at its core, about lifting the heaviest weight on a barbell across three lifts. Beyond this, I've found it builds as much mental strength as it does physical.
Of the various concepts and principles in the sport, I've found block periodisation to be the most helpful. Block periodisation is a way of structuring training phases depending on an individual's proximal goals. Modern block periodisation divides training into three timeframes: microcycles, mesocycles, and macrocycles. The structure of each timeframe may vary depending on whether one is preparing to compete or focused on building skill & addressing weak points.
Over the last year I've made it a point to periodise my life and my commitments. This could mean prioritising one aspect of my life at a time, or lowering my intensity to prepare for a time when I need to be more intense. As someone prone to burnout, it's been extremely vital to view things this way.
Periodising my life has also helped with balancing myopia broader-term thinking. A lot of us are prone to either focusing on the short-term, or a fixation on the long-term. Rather than view things as either, there's something about paying greater attention to each day, with an awareness that these will comprise the weeks, months and years in the future.
I've been working on a series called 'Barbell Philosophy' where I describe the copious mental benefits of pivoting, tapering, peaking and deloading beyond powerlifting. I hope to release this one day – provided I can get around to finishing it.
