This 30-minute upper body workout blends strength training with a Pilates-inspired burner to leave you feeling strong and sculpted. You'll move through two circuits of strength-focused exercises—think bicep curls to presses, rows, and tricep extensions—working for 45 seconds with minimal rest to keep your heart rate up. After repeating each circuit twice, you’ll finish with a Pilates flow burner to fire up your muscles and maximize the burn.

Equipment: 5-15 Dumbbells
