Tommy Cassano, founder of Outdoor Body, leads a 20‑minute, nonstop, full‑body HIIT workout filmed in Grand Teton National Park. The session is divided into four 5‑minute blocks: (1) Wild Flow – walking lunges, bear crawls, crab‑dip‑to‑toe‑touch, worm‑up, and squat‑jump crunches; (2) Core – high/low planks, side planks, sprint crunches, and various plank variations with a focus on “belly‑button‑to‑spine” engagement; (3) Boxing Cardio – jab‑cross combos, hooks, uppercuts, and power punches performed with proper stance, foot‑twist, and hip rotation; (4) Iso‑Glute – dolphin glutes, high‑plank glute curls, side‑raise pumps, and reverse‑lunge burnouts. Throughout, Tommy provides technique cues (core tightness, breathing, shoulder‑wrist alignment), motivational remarks, and vivid descriptions of the surrounding fall foliage, wildlife, and altitude. He encourages participants to scale the workout to a 40‑minute session, add mobility stretches, and respect the natural environment. The video blends instructional fitness content with outdoor inspiration, delivering an energetic, instructional, and nature‑centric experience.

Oh yeah, it's that glute isolation time. This is also core, so remember, always engaging belly button to spine. Over-exaggerate the process, squeezing tight. You gotta make it burn. If you don't feel it, if you're not burning, you're not working hard enough. You're not squeezing hard enough. So see, a lot of people do these with ankle weights, but at the same time, if you're doing this 1 minute nonstop and you're really concentrating neurologically on squeezing those glutes, you really don't need those ankle weights. But you can use them if you want. Here we go, 2, 1, nice. Other side, here we go, left leg.
