Jessica Biel is making a brave mountain climb...literally taking on 19,000 feet as she will scale Mount Kilimanjaro on January 7.

The 27-year-old actress will join Isabel Lucas and singer Kenna for the ascent and has been working with celebrity trainer Jason Walsh to prepare for the challenge.

Biel has been running stairs with 20 pound weights on her back and trainer Walsh says the sessions are nothing short of "torture".

"It was torture," says Walsh to Us Weekly. "She's going to eat it up!" he says of Biels' potential.

In an effort to help raise awareness toward the "life-threatening clean water crisis happening not only in Africa but around the world", the 7th Heaven star says she is addressing the problem by teaming up with Summit on the Summit for the climb.

“This is a basic human necessity that needs to be addressed now,” Biel said in an interview with GQ. "I've been training four times a week to get my VO2 [oxygen consumption] levels up to expand my lungs."

Adding about the journey, "We'll climb for a week straight, carrying 30 pounds on our backs. It's going to be intense."
