“I’m an Xterra triathlete and finished Beaver Creek a full 15 minutes faster than my previous time — while spending the same amount of time training. Manic three times a week. The results speak for themselves.”

Session structure

What a Manic HIIT session looks like.

Phase 1 · 10 min

Warm-up & Mobility

Targeted movement prep activating the joints and muscle groups for the session. Not generic stretching — specific preparation for what’s ahead.

Phase 2 · 40 min

Work Intervals

Rotating strength movements, cardio intervals, and functional exercises. Heart rate elevated. Muscles working across multiple planes of motion. Never repeated.

Phase 3 · 10 min

Cool-down & Recovery

Active recovery and mobility work to bring the body down properly and begin the adaptation process. This is where the work starts paying off.
