Curvy fitness influencer Crystal Chen built her career shattering gym stereotypes. After a recent break-up, she has little time left for men, instead finding joy in the gym - her place of power and positivity. Enter firefighter Scott Ritchie, the smug new guy who routinely steals her favourite squat rack. Soon, sparks start flying . . .

As the ultra-competitive foes battle for gym domination, the last thing they expect is to run into each other at their grandparents' engagement party. And, in the lead-up to the wedding, Crystal discovers there's a soft heart under Scott's muscled exterior. Bonding over family, fitness and cheesy pick-up lines, she just might have found her person. But when a photo of them goes viral, savage internet trolls put their relationship to the test . . . Are they strong enough to get through it?
