Talk about divine power.

Sister Madonna Buder doesn’t just have impressive strength and stamina for her age, but impressive fitness chops for anyone. In the latest ad from Nike, as part of its Unlimited campaign series, the nun is highlighted for insane feats of strength as the voiceover follows her as she runs, bikes, and swims.

At a cool 86 years young, the “Iron Nun”—who gained that nickname when she grabbed the world record as the oldest person to ever complete an Ironman—says youth has no age limit.

Sister Buder has been running since she was 48, at the suggestion of a priest, but has skyrocketed through her fitness goals over the past 30 years. She’s completed 325 triathlons and 45 Ironmans, which would be a feat for any athlete, but considering these have happened all over the age of 50 is wildly impressive. (Makes you think twice about skipping that morning workout, doesn’t it?)

“You carry your attitude with you,” Sister Buder told the Huffington Post. “You either achieve or you self-destruct. If you think positively, you can even turn a negative into a positive.”

If her title as the Iron Nun wasn’t enough to convince you that this sister knows what she’s talking about, her actions might. Check out the seriously inspiration ad from Nike, below, and maybe add an extra sweat sesh in this weekend?

Sister Buder is in incredible shape, physically, but running can improve your life in lots of other ways—beyond fitness. And remember, it’s incredibly important for every runner to prehab before they start their fitness journey.
