Imagine a giant rock, what is the most efficient way of lifting this rock (obviously without machinery)? The simple answer would be to use a lever, put the end of the bar under the rock and apply weight on the other end. The same concept applies to rowing. The blades are placed in the water (under the rock), and you pull on the blade handles (apply weight to the end of the lever/bar). The water is moved (the rock lifted) but more importantly the boat is pulled out of the water upon which it glides along. In this way the oar or a rowing boat is a lever. (as you can see rowing is a very technical sport since the rower has to understand all this and manipulate the given elements- the boat , the stroke and how they move the boat through the water-so as to be as efficient as possible and as fast as possible.
