The full title is Stan Lee Presents the Mighty Marvel Comics Strength and Fitness Book...
...but that was too long for the post header!
The book is actually pretty clever and its' use of specific characters for particular easy-to-do exercises is nicely done!
Written by Ann Picardo and illustrated by Joe Giella, this never-reprinted 1976 trade paperback from Fireside/Pocket Books was part of their extensive line of Marvel titles that included the original Stan Lee/Jack Kirby Siver Surfer: the Ultimate Cosmic Experience graphic novel, the four-volume Origins reprints series, and assorted individual character reprints as well as How to Draw Comics the Marvel Way and oddball titles like Marvel Fun Book and Mighty Marvel SuperHeroes' Cookbook!
