Catch up is a drill. A good basic all round drill that gets utilised a lot in warm ups and general swimming since we all know about it. Sometimes when learning to swim some go too far and it becomes their swim technique. Think about it – alternating single arms. One arm at a time, one stroke at a time. Not good for swimming fast. Mikey suffered from this and we chatted at the Olympic Pool last night about overcoming how his swim style was now a slow drill. If the arms can work together, one anchoring with a good pull on the water the other can be launched forwards with the hips involved. Swimming completely with the hands at 180deg to each other is going to be the fastest ‘stroke’ but can be pretty exhausting. A compromise can be reached.
