Quick Lower Body Strength with HIIT Circuits: Comprehensive 20-Minute Leg Day

Workout focused on strengthening the lower body using high‑intensity interval training (HIIT) style circuits. In the video you’ll see them demonstrating a series of exercises designed to work muscles like the glutes, quads, hamstrings and calves through repeated bursts of movement with short rest periods, combining strength‑building moves with elevated heart‑rate intervals to both build muscle and get cardiovascular benefit. The pacing is upbeat and instructional, with the creator guiding you through each exercise and often counting reps or timing intervals so you can follow along for a full lower‑body workout session.
