In general, what body shape is best suited for swimming? If you think there is one, what shape would that be and why is that shape the best? I’ve added a few shapes to give you a list of options, or if you feel like it, come up with your own. Adonis… as in broad shoulders, slim hips and rippling muscles. Skinny… as in lean muscle and sinewy. No waist… as in very little difference between the size of the hips, waist and shoulders. Pear shape… hips slightly bigger than the shoulders. Glenn Mills shape… no description available.
