Today H&M released a new activewear collection called For Every Victory, along with an inspiring new video narrated by H&M Sport ambassador Caitlyn Jenner.

"I felt like I couldn't do it alone, or with the entire world watching my every step," the 1976 Olympic gold decathlon champ says in it.

"I fought to belong, and for my right to be different. I felt trapped by my body and by what others expected of me."

She continues: "I had to find strength within me that I didn’t know I had. I questioned whether it was really worth it, nothing came easy. But nothing truly important ever does. To keep going no matter what the obstacles is, is what victory looks like. Whether you are representing your country, or yourself."

Jenner added in a statement that she's "proud to be part of the For Every Victory campaign" because it reminds her of "the strength and bravery of people around the world to be their authentic selves and overcome any obstacles that may come their way."

Also included in the new campaign are members of the Kings Cross Steelers, the first-ever gay inclusive rugby team.

"For over 20 years, the Steelers have been helping hundreds of gay and bisexual men to build confidence and strength of character through the sport of rugby," Christopher Kang, a member of the team, told Gay Star News.

"Perhaps due to our history and place in the community, we were approached by H&M about getting involved in a new ad that celebrates sports and diversity. We were honoured to be asked and the guys really enjoyed being a part of it…despite having to spend a cold March day standing around in kit!"

Check out the new ad below, as well as an extended interview with Jenner that covers what she thinks is her "biggest victory of all."
