Wow, we're still trying to catch our breath!
Zac's strength, focus, and determination is absolutely AH-Mazing to witness as he pulls himself along a rope strung above 150-foot ravine!
We aren't sure what was more distracting…Zac Efron's hot bod or the 150-foot drop!
If you're wondering why anyone would do this, let alone a celeb like Zac, the adrenaline junkie is one of six stars who signed up to hang out with British adventurer, Bear Grylls, for a new reality show on NBC.
Zac is apparently a HUGE fan of Bear so we have a feeling he jumped at the chance to be on the series!
We can't wait to check out the premiere of Bear's show…and to see more of Zac's muscles put to the test!!
