core trainning

Question
can core trainning improve my dolphin kick, if so what exercies do you suggest?

Answer
Yes--core training can help.  The best exercise in the pool is to do dolphin kick on your back with your arms above your head(streamline position)and work both the up and down movement of your kick.  On dryland any crunches, leg lifts etc.
Any exercises that work both your abs and your lower back muscles are good.
Hope this helps,
