40 min. CLASSIC Lower Body & Abs Strength Training

This 40‑minute lower‑body and abs strength training routine uses dumbbells ranging from 20 to 45 lbs. It consists of two rounds of bilateral and unilateral leg exercises followed by an abs round. Each round follows a work/rest cadence: 55‑second work with 30‑second rest for the first round, 45‑second work with 30‑second rest for the second, and 30‑second work with 10‑second rest for the abs set. The workout targets glutes, thighs, calves, and core, and is designed for muscle building.
