Make sure to warm up before this HIIT workout (here's a quick sequence that'll work), led by celeb trainer Faisal Abdalla. The first three exercises have you holding the dumbbell overhead (hellooo, shoulders), followed by more multi-muscle groups moves like goblet squats and low-to-high woodchops. You'll repeat the circuit twice through for major burn!
