Muscles & Monsters

Tegan, a baker, has a wedding cake disaster and is helped out of it by Atlas, a wolven who owns Leviathan Fitness, a gym staffed by monsters. He offers to help her lift, and she signs up for a membership herself because she wants to get stronger.

As his training sessions turn into something more, the two have to work out how much their new relationship can carry, and whether Tegan is the mate Atlas has been waiting for. Muscles & Monsters is the first book in Ashley Bennett's Leviathan Fitness series of monster romances, told in dual points of view.

It was first published in 2022 and reissued by Berkley in a revised and expanded paperback in 2026. Reviewers describe it as cozy, low-angst and spicy, with a plus-size heroine and a gentle, wolfish hero.
