The 8 Best Full-Body, No-Equipment Exercises, According to Trainers

"Lunges hit 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."

1. Start standing, with your feet hip distance apart.
2. Keeping your core engaged, step out to the side with your right leg, bending your right knee at a 90-degree angle, and keeping the left leg straight. Make sure your right knee is directly above your ankle; you should be able to see your front toes.
3. Push back up to the starting position and repeat the lunge on the left side. This counts as one rep.
