Rihanna has mastered the art of perfecting her curves. In the best physical shape of her life, the singer revealed to Vogue magazine that the secret to her luscious yet toned body is a RealRyder, a spinning bike with handlebars that move laterally. Her trainer Ary Nuñez uses that machine to slim and tone her core, while weights strapped to her hands helped her multitask and work out her arms. “I hate going to the gym and doing it the old-fashioned way,” Rihanna tells the magazine. “I hate anything that’s too straightforward, too routine, too familiar. I get bored really, really quickly.” If you have a short workout attention span too, switch your routine up to stay engaged.
