My daughter twirls and spins without inhibition and without giving a hoot as to who is watching or where she is. The kid next door jumps simply because she can. She jumps off cots, sofas, stairs, anything really. Kids do skin the cats on rusty monkey bars because they can. 

They move with a sense of wonder and fascination simply because they can. There is no deeper meaning, philosophy, finding peace, better body composition or agenda for them. It’s just fun and they do it because they can.

Behind all the science about contractions, sets, reps, exercise selection and gym equipment there is a really simple truth: 

If you are not absolutely blown away by what your body can do, you might never find the motivation to do what your body is capable of doing.
