I challenged myself with stair sprints 10 flights up, 2-minute rest And repeat. At beginning I hated it my lungs burned, my legs were jelly and I thought I’d never survive a second round. But week after week my endurance improved And now I crush the stairs like a beast and the post-workout high is insane. Stair sprints aren’t just about building stamina they teach your body and brain that you’re stronger than you think.
