Pumping dumbbells through curls and presses, Riss sweats in her sports bra and leggings

Riss works out in a bare white room, wearing a black sports bra and black leggings. She curls dumbbells standing, then lies on the floor to press them straight up over her head. Back on the floor she grinds through seated leg lifts, bracing on her hands with her core pulled tight. Side-on, she curls a dumbbell toward her shoulder while her ponytail swings with each rep. She sinks into a low squat, thighs trembling, then rises back up. Grey dumbbells and a water bottle sit on the floor near the wall.
