Olympic champion Rosie MacLennan speaks candidly about how she came to accept her body in the competitive world of trampoline gymnastics.

The first time trampoline gymnast Rosie MacLennan competed for Canada on the international stage, her focus wasn't on her routine.

Instead, looking around the gym that day, all the 17-year-old could think about was how out of place she felt next to her smaller, slimmer competitors.

"I remember warming up and looking at the other athletes, and looking at myself, and feeling a little bit uncomfortable," said MacLennan, now 27. "It's not what you should be focused on before you get up and jump on a trampoline 20 feet in the air."

Today, MacLennan is the reigning Olympic trampoline champion — and proud of her body. Her build — five feet two inches tall, with powerful legs — has proven incredibly effective at generating the energy she needs on the trampoline to propel her into the difficult twists and flips that earn top marks.
