How to do an alternating forward lunge with biceps curl:
- Stand tall with your feet hip-width distance apart. Hold a dumbbell in each hand at your sides.
- Step forward with the right foot as you bend the elbows in a biceps curl. Lower your hips until both knees are bent at about a 90-degree angle. Keep the front knee directly above the ankle, and lower the left knee to just tap the floor.
- Keep the weight in your heels as you push off the front foot and step it back to the starting position. That's one rep.
