Did legs on Tuesday night and have trouble sitting down and walk around like an old man...
its because u go too many days without training them bro trust me on this one
do a full body everyday that way u keep everything limber and ABLE everyday
dont fall in the mind trap of one day of legs here and there. do a full routine everyday and you will will adapt and recover faster and wont be all fucked up and sore
every day off from a muscle group...that muscle group tightens and stiffins up and loses its flexibility and likley to produce too much lactic acid when u train it sparadically. training everything everyday u clear your system everyday. lactic acid is toxin buildups to an extent
so the toxins in your legs are sitting around in your legs the more days u go without training them compounding the problem
