Get ready to sculpt and tone your muscles in just 35 minutes with two sweaty circuits of HIIT. You'll repeat each circuit three times, followed by a 30-second burner before moving to the next circuit. This way, you'll build tension in the same muscle groups using movements like weighted side lunges, rows, chest presses, and leg lifts. The workout also includes a warm-up and cool-down to complete your routine.
Equipment: 5-15lb dumbbells
