Strict vs Kipping

Kipping can be the subject of ridicule by some, but what are the benefits of the kip? Are you more susceptible to injury through, say, the kipping pull up rather than strict? Jowsey, Phil and Jemma discuss the virtues of both movements.   

“The front squat, overhead squat and back squat smell like each other but they are not the same. They are called a squat but are very different… centre of gravity, muscular activation patterns etc… Should coaches be viewing kipping and strict as two different exercises? Should we be drawing a line between them, one doesn’t precipitate another… they are different exercises?”
