Static Lunges target your glutes, quadriceps and hamstrings. The majority of your weight will travel down through your front leg, whilst your back leg along with your core take the role of stabilising your body preventing you from moving about side to side.
You should aim to look ahead and ensure that your front knee is not coming further forward than your toes.
If you're doing this with a barbell, set up with the bar in a comfortable position on your back, with your hands nice and close into your body. Take a few steps away from the rack so you aren't at risk of hitting it. From here, you can step forwards or step backwards to get yourself into a strong starting lunge position. Whilst keeping both feet still, bend your knees and come into a full lunge position before pushing back up again.
