One of the smartest strategies around the gym this week: practice loading and unloading the bar for your deadlift. As Jess King pointed out, learning to slide plates on and off faster means you may get an extra attempt or two in Event #1.
No one comes into the CrossFit world as a solid all-around athlete. We try to ferret out strengths during OnRamp, and address weaknesses as soon as possible, but don't worry: no one wakes up one morning with a 400lbs deadlift. Runners slam to a stop when given their first clean and jerk; powerlifters turn all pink when they see more than 5 reps on the chalkboard; gymnasts can't stick the landing at the end of a 12-minute METCON.
A 500lbs-deadlifter isn't going to have much fun on that mile. And a marathoner may have all the time in the world, but isn't going to break 200lbs off the floor. But take a GOOD lifter, make them a GOOD runner, and give them the sense to practice loading and unloading the bar, over and over, every. damn. day? Could make for a winner.
Yes, athletic background counts for something. But brother, it ain't the only thing.
Yes, others have had a head start. They're born athletes. Their parents made more money than yours. They've been doing this for longer. They're starting life from the womens' tee. You can complain about your handicap, or you can work on your drive.
