Resistance Band (RB) Lunges train your quadricep muscles (front of your upper leg), hamstrings (back of your upper legs), glues (your bum), and your core muscles (abdominals and lower back).
Maintain a stable stance throughout the exercise by keeping one foot in front and one foot in back (at shoulder width), spine completely upright, and core muscles (abdominals and lower back) engaged throughout the entire exercise.
Step into a stable position with your weight evenly balanced front to back and left to right. Inhale as you lower your body down by bending both knees to 90 degrees. Exhale as you use your front leg to push your body back up to starting position.
Keep your body straight and tall by sinking your hips, looking straight ahead, and not bending your body forward. The motion of this exercise should be primarily up and down, not front to back or left to right.
Grab the resistance bands at the very end for the least intensity. Grab the resistance bands at a shorter length to increase intensity.
You can also perform the lunge as a bodyweight-only exercise by resting your hands on your waist.
