Wait, you really thought that level of soreness was just how it's supposed to be? No way, man. That sounds brutal, like your body was screaming at you every night. A quick stretch seems like a no-brainer compared to that.
Our foreman made us do five minutes of hamstring stretches last year, and it totally changed the game for my lower back. I still do that routine before every job now.
Honestly, who even considers stretching before a day of bricklaying? I used to just jump right in and thought the soreness was normal. Trying a quick stretch first really does cut down on the next-day aches.
