i fully believe in private coaching time if you can afford it. someone right there watching everything you do is invaluable. there is no other way to know exactly what you’re doing right or wrong. INSTANT feedback and feeling the difference is what you need.
if you’re in the houston area, down on the south side of the beltway is 3rd coast training. im FAR from a “good” swimmer, but i went through the 6 private lessons at 3rd coast to get the basics down and i went from flailing around like a dead fish to feeling completely confident in the water but not yet speedy.
