Need to elevate your workout routine? Want to get your heart rate up outdoors?
Why not draw inspiration from some future members of the U.S. Marine Corps and head to one of Colorado’s most iconic outdoor landmarks to work out, Red Rocks Park and Amphitheatre?
Nearly every Saturday, Sgt. Ken Bremer, a Marine recruiter who works with young people from Golden to Leadville, brings future service members to Red Rocks to get them fit fast.

Yes, this natural amphitheater is known best for its perfect acoustics, spectacular scenery and legendary concerts with bands like The Beatles, U2 and The Grateful Dead.
But the red stone steps and rows of seats carved back in the 1930s and 1940s by other young corpsmen – members of the Civilian Conservation Corps – also provide the perfect place to build strong bodies and healthy hearts.
West of Denver, Red Rocks sits in the foothills at 6,450 feet above sea level. The 738-acre park opened in 1941 and along with the amphitheater, Red Rocks boasts hiking trails and multiple monolithic rock formations.
On Saturdays, Marine recruits known as “poolees,” show up in matching T-shirts. They do pushups and relay races up and down the stairs and across the rows as trainers shout words of encouragement: “Come on! Pain is weakness leaving the body!”
Bremer said he loves bringing the young people to Red Rocks for intense workouts.
“We live in the beautiful state of Colorado. Why not come to one of Colorado’s great places to work out?” he said.
Bremer trains many young people who have never worked out.
“Some can’t do one push up. We build up the mental capacity to push yourself. A lot of it is mental fortitude. You’re stronger than you think you are,” he said.
Elijah Avila of Grand Junction, graduated from boot camp a year ago. He was always athletic and did martial arts and baseball in high school. He said he likes group workouts because they push him harder.
“Seeing all these other people motivates me.”
And exercising outdoors is literally a breath of fresh air any time of year in Colorado.

“I feel free being in nature,” he said.
