In this series of clips, we'll watch Bruno from head-on. Bruno starts very slowly, and we see his attention to detail at the front of the stroke. The lead arm is aimed directly forward, piercing the water with nearly his entire body hidden behind the hand. The rotation is extreme, getting his body completely on its side. Bruno is focusing on reaching the longest line possible and balancing his body as it becomes as small as possible on his side. Above water, Bruno has a relaxed recovery with slight bends in his elbows. Bruno's pull initiates in a very straight arm fashion. This is more common in world class sprinters, and something to step towards very slowly. It takes years of training both in the water and out of the water to build up the muscles to be able to do this without injury. Bruno picks up the pace just a bit, while still focusing on huge rotation and exaggerated extension. Again, he initiates the catch with a bit more straight arm, which also starts to give him a bit of lift to keep him higher in the water. Above water, the arm is still relaxed with a slight bend in the elbow. At top speed, Bruno has less rotation but still reaches a complete extension on both sides. The arms spend a little less time in the straight line, as he catches the water as quickly as possible, thinking of getting on top of the elbow for a bit earlier power. His arms remain relatively straight through the arm-pull, giving him greater hand speed. We can see the effort that he puts into reaching full extension on each stroke, almost like he's grasping for as much water as possible. From above water, we now see that Bruno throws his arms from the finish of each stroke to the start of the next. By throwing the hand, this also creates a faster rotation of the body. Bruno tries to recover with so much force that the act of the hand hitting the water helps to drive his body forward.
