The lunge is a great single leg compound exercise which will help achieve awesome results in muscle mass. A lot of people like to use this instead of good old squats but I like to use both in my leg workouts as they work your legs differently. The lunge is different to the squat because as you move forward through the air in the execution your muscle has to decelerate before landing and contracting again.
We are really targeting our quadriceps with this exercise but our gluteus maximus will be working synergistically and our hamstrings come into play as a stabiliser too. So, a very good all round exercise.
The lunge is also a fantastic dynamic stretch action so not only are you breaking down your muscle tissue, you are incorporating flexibility and improving your function also. A more functional athlete will be able to lift more. The beauty about lunging is you don’t need a squat rack so you can perform this exercise anywhere. It is also a very diverse exercise as you can adapt the technique to hit different areas of your legs.
The Technique
Stand with your feet together with your torso in an upright position. Look ahead with your toes pointing forwards. Core stabilisation is very important here so switching on the TVA (Transverse Abdominals) muscles is a good idea. Breath in and relax while keeping your abdominals contracted (you may need to practice this). You can do this exercise with your own bodyweight, technique is very important so only start adding resistance once you feel comfortable doing lunges (with good form). Imagine you need to step over an invisible box in front of you, this is a good mindset to ensuring you give yourself a good step forward. Land on the heel of your foot then load onto the forefoot. Your knee should be in line with your foot and slightly over your toes. Return back to the starting position by driving through the leading quadricep. Alternate with other leg and repeat.
Like I said this exercise can be very versatile. You can change the angle your front foot lands, this will recruit your muscles differently and keep them guessing (which is the key to continual gains). You can also change the tempo, so if you were to slow down the pushback you are increasing the intensity of the exercise by keeping your muscle fibres under tension for longer. The one most bodybuilders will go for is adding resistance, this can be achieved by holding dumbbells in your hands or placing a barbell across your traps. I do not recommend using too much weight with this exercise, it is normally under-estimated, people new to this exercise will get great gains to start with using their own bodyweight.
