Reps - What Are They?

The Rep Is The Most Important Loading Parameter.
It determines the amount of sets, rest, tempo and number of exercises.
It even influences exercise selection. For example reps between 1-5 are more for neural adaptions of the nervous system and typically involve Olympic lifts such as power cleans and pulls and major compound exercises. Doing singles or doubles with dumbbell kick backs is not very productive or demanding but the same can not be said for Front Squats or Snatch Grip Deadlifts!
When designing programs first the end goal must be determined such as neural adaptions for pure strength, fat loss, hypertrophy each will require a different rep bracket. Then the athletes genetics need to be taken into account.
Its the first variable when individualizing and periodising workouts for athletes, weekend warriors or physique athletes.
