Some exercise will challenge many components of your fitness ability. The exercise demonstrated above is such an exercise. This exercise is regarded as a high value exercise (HVE). When you can do lunge walking with dumbells the next level up would be lunge walking with barbells. If you have good balance performing barbell lunge walking, then a higher level would be performing lunges stepping on and off a low stepper gradually building up to a high stepper.
Barbell High Stepping Lunges as performed in the video above will challenge your muscular strength, your balance, your flexibility and your coordination. If you perform the exercise for high reps it will also challenge your muscular and cardiovascular endurance. It will work wonders if you are trying to get a tighter butt with lean sexy thighs
Why only do exercises that no longer challenge your fitness? When you are no longer being challenged you will reach a plateau which will bring your lean muscle building, fat burning program to a screeching halt.
Challenge yourself by always striving to perform more (HVE) high value exercises.
