There are four kinds of forward starts: the traditional grab start and three variations of the track start, including a leaning forward track, a full backward track, and a medium backward track. Swimmers should try each one of them and use the one that works best for them. Generally, track starts give swimmers more stability on the block, and both of the leaning back track starts allow the swimmer to use the arms to pull against the block for momentum. They also create more impulse, or greater time of force applied against the block. The forward track start is the quickest to the water but the least powerful. The full backward is slowest of the block, and often the back leg is bent to an extreme that compromises the power that the start produces. The medium backward splits the difference - it is quick and powerful.
