Tommy Cassano, founder of Outdoor Body, leads a 20‑minute nonstop "Peak Fusion" workout filmed on the shores of Lake McDonald in Glacier National Park. The session is divided into four five‑minute blocks: boxing, full‑body, "Wildflow" (a mix of lunges, crunches, jacks, and yoga‑style movements), and core. Throughout the video Tommy provides real‑time cues, timing counts, and modifications while highlighting the scenic setting, temperature, and natural features of the park. He emphasizes core engagement, glute activation, and proper form for each movement—boxing combos (jab, cross, hook, uppercut), burpee variations, single‑leg squats, power lunges, sumo burpee, hip‑dip leg raises, figure‑8 rolls, and more. The tone is high‑energy, motivational, and conversational, encouraging viewers to push hard, stay tight, and enjoy the outdoors. The video concludes with a reminder that the routine can be repeated or extended, and an invitation to visit Glacier National Park.
