you do something, your body wants to do that particular thing as efficiently
and effectively as possible so it strengthens you in those areas, also known as
adaptation. Once you adapt to a program, your body stops changing and you hit a
This is very common for people who want to get fit so they decide to
take up running. Well, they get out there and run 5km, 3 days a week and see
great results the first few weeks, losing weight, etc. Then, all of a sudden as

are great, you can constantly swap out different moves and literally have an
infinite number of exercise combinations to keep your body constantly
guessing...and constantly changing!
On the other hand, if you are an athlete who wishes to improve a certain skill or attribute - leg explosiveness for example - repetition is the way to go. Sure, you still want to formulate a program around variation to improve over time, but you also need repetition to give your body or specific body part time to adapt and master a certain skill set.
