"Lunges hit major major muscle groups all around the body including your glutes, hamstrings, quads, back muscles, and abs," said ACE-certified trainer Bianca Grover of Bianca Grover Fitness. "Because they split your base and require balance, this is a great way to push yourself without the weights."
- Start standing, with your feet hip-distance apart.
- Keeping your core engaged and your torso upright, step forward with one leg, lowering your hips until both knees are bent at about a 90-degree angle. Make sure your front knee is directly above your ankle; you should be able to see your front toes. Your back knee should hover just above the floor and your weight should be in your front heel.
- Press your front heel into the floor as you push back up to the starting position. This counts as one rep.
