Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The chest of Maharaja Prthu was very broad, his waist was very thick, and his abdomen, wrinkled by lines of skin, resembled in construction a leaf of a banyan tree. His navel was coiled and deep, his thighs were of a golden hue, and his instep was arched.
