I have been learning to swim (only freestyle) from last December 2016.
When I try to take a breath, my head is under water and I end up either drinking water or stop swimming.
My coach tells me there are two things which are wrong when I swim
- Keeping the hand in cupped posture - bad form
- Keeping the lower back tensed.
Through conscious practice I can overcome the first one, but for relaxing my lower back (hips), I do not know what to do.
Coach is telling me that, it is for this reason that my body does not stay afloat when in water.
Are there any specific drills or exercises that can help?
