After dryland exercises and sculling drills Coach Gary teaches Noah the late breath breaststroke using the dolphin drill.  Because this technique requires a high velocity of the up and down movement  we begin with a normal technique and progress to a late breath technique.  It's important to develop this skill slowly in order to maintain efficiency.  Holding the head underwater reduces frontal drag by a significant amount so in theory a late breath breaststroke will be faster than an early breath however being comfortable with this technique requires a lot of flexibility and timing.  Most swimmers know the dolphin drill but coaching this in a way that emphasizes a fast up and down movement creates a whole new dimension to it.
