when i read that article, all i can think of is kingfish.
Squat daily! 4xxlbs Plus is attainable!
but that HIIT shit... is really crazy shxt that really hurt me to some extend.
having said that, one of my friend is asking me to do it with him tomorrow...
(and have all u can eat sushi afterward.... )
eat sushi first.. then do HIIT.
I like every day squatting.. but I also don't think it has to be as heavy as most people prescribe.
going light mostly every day, and heavy during more important sessions, is probably much more effective for ATHLETIC PERFORMANCE than going heavy every single day. Going heavy every day will make you a much better weightlifter/powerlifter, and also possibly burn you out.. Knowing your body and how you recover is absolutely essential. But for athleticism??? Squatting light every day using a variety of set/rep schemes is probably even more effective .. because we're just talking about stimulating the cns without taxing it, recruiting motor units, causing some small amounts of hypertrophy, great for recovery, targeting key muscle groups (p-chain, quads, core), improving strength & depending on what set/rep/tempo schemes you use - also improving explosive strength etc.
It's kind of like if we were to jump/sprint every day.. does it have to be max effort? it most likely can't be.. risk of injury increases considerably.. so if someone does daily sessions (incorporating rest when needed), many of them will have to be submax.. but then out of nowhere you will feel amazing and want to push yourself to the max. Same concept would apply to lifting every day; mostly submax, then push yourself (max or training max (no psyche up etc)) when you feel great.
