As discussed earlier, range of motion (ROM) is key. Anything less then full ROM doesn't count in our minds. Only with proper ROM do you elicit maximal power out-put, and in Crossfit, Power is King! Many people do not complete exercises through the full ROM for many reasons. It hurts, it takes more effort, it takes more time and they can't lift as much weight. Some people have flexibility problems and some lack the kinesthetic awareness, not knowing that they are high on their squat or their hip isn't reaching full extension.
"Power is the independent variable most commonly associated with the rate of return on favourable adaptation." -Greg Glassman
If you're not giving us full ROM, you're doing less work, you're producing less power, and we are NOT going to count your reps.
