Supercompensation occurs when you lift hard enough for a period of time that your body can’t recover from. You get to a point where you’ve lifted so hard that you’re now 10% weaker than when you started. You deload for a while and, voila, you surpass your former self because fatigue dissipates faster than fitness. An example is Bill Starr’s advanced 5x5 method.
My question is: Why wouldn’t you work out with significant intensity/volume every single day? Even multiple times a day? This would undoubtedly put you in the hole much faster. Then deload for however long it takes to allow full recovery. It should get you to your goals quicker shouldn’t it? Makes perfect sense.
(I imagine there’s a reason most elite lifters don’t do this… John Broz excluded)
