The group that makes you better.
Certified instructors. Coached every rep. Six programs built around Form over Frequency — because how you move matters more than how often you move. Serving the Denver south metro since 2010.
The four things that actually drive results.
Research is unambiguous: coached training outperforms self-directed exercise across every outcome metric. Here’s why every Denver HIIT class is instructor-led from warm-up to cool-down.
Form over Frequency
How you move matters more than how often you move. Correct mechanics produce results. Poor mechanics produce injuries. Every rep at Denver HIIT is coached.
Progressive Overload
Your instructor tracks your progress and increases challenge systematically. Random workouts plateau. Programmed progression doesn’t. You’ll always be working at the edge of your ability.
Working Around Injury
Injuries don’t stop your training — they change it. Certified instructors modify every movement for current limitations so you maintain fitness and momentum.
Group Accountability
You show up when people expect you. You push harder when someone is next to you. Group environments consistently produce higher effort and better long-term adherence.
Every program. One private facility.
Five expertly coached offerings under one roof. Each one instructor-led, structured, and designed to produce real results for a specific type of athlete or fitness goal.
Manic HIIT
60-minute instructor-led high-intensity interval training. Strength, endurance, balance, and flexibility. Zero repeated workouts.
LIFT
Coached group strength. Progressive programming. Movement quality first, intensity second. The foundation everything else runs on.
Yoga & Mobility
Certified instructor yoga and mobility. Breath work, joint health, and recovery that makes the rest of your training last.
Senior Mobility & Strength
Not a gentle class. Real programmed fitness for active older adults who want to stay strong and mobile for decades.
Youth Athletics
Sport performance and conditioning for young athletes. Speed, agility, strength, and mental toughness under certified supervision.
Personal Training
Custom programming and coaching applied exclusively to your goals, schedule, and history. One instructor. One member. One goal.
Real members. Real outcomes.
“Before Manic I’d completely plateaued. A year later I won the downriver race through Gore Canyon — and the race coordinator asked if I wanted to paddle for the national champion rafting team.”Sarah Hamilton · Competitive kayaker · HIIT member
“Xterra Beaver Creek — 15 minutes faster than my previous time. Same training volume. Three Manic sessions a week instead of solo gym time. The coaching and group energy make every session harder than I’d push myself alone.”David Kinzel · Xterra triathlete · HIIT + LIFT member
“After a serious knee injury I thought my active life was basically over. The instructor modifications kept me training through recovery. Nearly 100 workouts in — strongest I’ve ever been.”Rachel Short · Semi-pro water skier · LIFT member
