In this 35‑minute instructor‑led HIIT class, Lindsey Baumgren (Nourish Move Love) guides participants through a core‑focused cardio workout that avoids traditional crunches and instead emphasizes spinal stability, anti‑coning, and functional movement. The session is organized into a dynamic warm‑up, three timed circuits with decreasing work‑to‑rest ratios (45/15, 40/20, 30/15 seconds), and a cooldown stretch. Each circuit blends bodyweight and weighted moves—bear‑crawl/down‑dog flows, load‑transfer lunges, single‑leg dead‑lifts, dead‑bugs, cross‑body mountain climbers, wood‑chops, towel/sliders, and a one‑minute single‑arm plank burnout—while a modifier (Rachel) demonstrates low‑impact alternatives. Throughout, Lindsey provides detailed cueing on breathing, rib‑cage engagement, hip‑drive, and mental focus, reinforcing the core’s role as the body’s foundation. The workout culminates with a high‑intensity “dirty 30s” finisher and a full‑body stretch, encouraging participants to push limits, adapt intensity, and develop functional core strength.
