The lunge is a simple exercise that targets the legs and glutes. Here are the steps to perform it correctly:
Stand with your feet shoulder-width apart and your arms by your sides.
Take a big step back with your right foot and lower your right knee until it almost touches the floor. Keep your left knee bent at a 90-degree angle and your torso upright.
Push through your left heel and return to the starting position. Repeat with your left foot stepping back.
Repeat with your left leg and alternate sides for the desired number of reps.
