Colorado Springs sits above 6,000 feet, where each breath delivers roughly 20 percent less oxygen than at sea level. That makes cardio genuinely harder, especially for newcomers, but it changes strength training far less than people assume. Lifting is short-burst work that does not depend on oxygen the way sustained cardio does, which makes it the smart constant in a Springs training week.
Here is what altitude actually does, and does not do, to your workouts.
Why does cardio feel harder here?
Thinner air means less oxygen per breath, so your heart and lungs work harder at any given pace. Visitors notice it immediately; even longtime residents have less aerobic headroom than they would at sea level. If you have ever wondered why a flat walk that would be easy elsewhere leaves you puffing on a Springs trail, that is the whole story.
Does altitude hurt strength training?
Barely. A set of squats or presses lasts well under a minute and runs primarily on energy systems that do not require oxygen in the moment. You may breathe harder between sets and want slightly longer rest, but the weight on the bar does not care about elevation. This is why our 55-minute coached sessions at Alloy Colorado Springs work the same for a newcomer from sea level as for a Springs native: the program adjusts rest and pacing to the person, like everything else.
Is there an upside to training at altitude?
A modest one. Living and training up here gives your cardiovascular system a mild ongoing stimulus, which is part of why elite endurance athletes train in Colorado Springs. For everyday adults, the practical takeaway is simpler: build strength indoors year-round, and your hikes, ski days, and travel workouts all feel easier.
What should newcomers to the Springs know?
Give yourself a few weeks of grace on anything aerobic, hydrate more than you think you need to, and do not judge your fitness by your first week here. Strength training is the ideal way to stay consistent while your body adapts, because it is the format altitude affects least.
Frequently asked questions
Should I train differently at altitude? Slightly longer rests between sets at first, and more water. A coach who watches you train will handle both without you thinking about it.
Will I get sore faster here? Soreness comes from the work, not the elevation. A properly scaled first program keeps it mild either way.
Does altitude burn more calories? Marginally, and not enough to build a plan around. Consistent training and sensible eating still do the heavy lifting.
