If you haven’t read the first post, it might be a good idea to do so, but hopefully this won’t be too technically focused that it doesn’t make sense. To summarise, this makes for such a good postural exercise because it engages and exercises the glutes and hamstrings of the front leg, while stretching out the quads and hip-flexors of the rear leg, whilst under load. Why that is a good thing will hopefully become apparent.
Of course, my first recommendation for anyone is always to do what they find helpful. This is an exercise, a technique, and as such it might be something you find helpful, or it might not. For many people it is too challenging to be helpful, and for others it is too easy. Never mind - your ability to squat does not reflect on you as a person, despite what some would have you believe.
It can also be quite emotional - the fetal position is comforting, and when you stretch the thigh back and open up through the front of the hip, when you reverse the fetal position, it can feel exposing and unsafe. If you’re training in an unfamiliar environment, it’s one of many things that can contribute to anxiety. But ultimately it can be good for you too, as long as you’re training on your terms. We are bullied into training far too often for my liking.
Basically, this exercise – when taking leverage and coordination into account – supports hip mobility and helps to correct muscular dysfunction of the lower back. Tight hip-flexors and/or weak glutes - relative to your other muscles - often results in lower back pain and immobility, so the impressively-named Bulgarian Split-Squat is pretty much good for everyone... Unless of course you can’t do it, in which case there are other, easier exercises that can help. Maybe a topic for another time.
On a different, but related note – we’re often told lifting weights will make us tight, but as with all things - it isn’t the weight itself, it’s how you train in relation to your own mobility. When I started squatting deeply with heavy weights, extending through my hamstrings under load, my front splits improved. I’ve never quite been able to touch down to the ground in a split, but when I built up the strength of my hamstrings in an extended position and then went back to training my flexibility, when practicing the splits I felt stronger, so I didn’t feel so vulnerable extending into my deepest split. I couldn’t go that much lower than before, but I could certainly get there a lot more safely.
Anyway: the Bulgarian Split-Squat, or Lunge (with back foot elevated) – we’ll start with foot positioning of the back leg, then the front foot, and then work our way up the body.
If your foot is flexed, try to apply even pressure through the ball of the foot, and don’t let the ankle roll out or in. The foot should be facing straight forward, with the toes and heel aligned with the knee, not out to the side which only applies unwanted pressure to the ankle. This position already requires a degree of flexibility and strength in the ankle joint, and so, a pointed toe might be better.
The position of the front foot is determined (again) by your flexibility. At all times, your front heel should be pressing into the ground. If the heel lifts off the ground, or even if your body’s weight moves forwards to your toes, this will make it harder to balance. If your stance is too narrow, the knee will come forward beyond the toes, and this will move the workload into the quadriceps rather than the hamstrings and glutes, so again it’s all about leverage. Likewise, if you don’t squat down very far, you’re not giving the glutes and hamstrings an opportunity to work. If you lean the torso forwards and lunge only slightly, it’s just going to be a front-leg quads work-out and isn’t going to deliver the benefits this exercise is known for.
So your foot needs to be far enough forward that when you’re down in the bottom position of the lunge you can still drive through your heel – you don’t automatically shift your weight forwards – but if your foot is too far forward, it’ll limit how deeply you can lunge.
For balance, foot stability and strength, I recommend training in fairly minimalistic footwear. If you’re not able to train barefoot, and many of us aren’t, try to use something flat-soled, that allows you to have an actual tactile experience of weight distribution through to the ground. Many companies make barefoot-inspired footwear these days, but an older-styled pair of Chuck Taylors or Dunlop Volleys or simple flat-soled canvas sand shoes are much cheaper and will serve your purposes perfectly well.
When you press the inside edge in particular of the ball of your foot down, it helps you to stabilise. When you lift up the arch, it helps you to develop strength in your feet, and it helps to pull the knee out where there’s less chance of it collapsing in – this is a better position for leverage and stimulating gluteal activation. And of course, when you press your heel down, you’re much more grounded, able to squat deeper, and your balance will benefit remarkably. So in the one foot, you have two clear points of pressure, and one point of pull in between them. Clearly there are a lot of things to be aware of in the action of the front foot alone.
The front knee, as I mentioned, should be pulled slightly to the outside, this feeling and the feeling of lifting the arch are linked. It’s the glutes that stop the knee from collapsing inward (or, to be more specific, the femur from internally rotating), so if you cannot keep the knee straight or pressed slightly out that’s okay, there are other things we can do for the glutes.
Whether you think of lifting the arch, or you think of engaging the glutes to keep the knee from collapsing in, might not make much difference. You can come at knee alignment from the feet or the hip, depending on you. This is a point I’ve been paying more attention to in my own training, but what helps you best might not be what helps me best.
If the torso and the shin of the front leg stay vertical, this will serve you best. If you feel a pinch in the lower back, you might be resting the back foot on a step that is too high. The back will pinch and compensate for tight hips by arching excessively as you try to keep the torso vertical. Lower the step until you have developed your hip mobility/flexibility some more. You can also squeeze the abs to brace the lower torso – whatever works to stop your lower back from feeling like it’s collapsing or arching too much. But oftentimes – rather than select a lower step or exert more force to brace consciously – people simply lean forward and don’t observe the changes in leverage and muscle activation, and so they miss out on the strength and mobility benefits, and ultimately won’t progress as far as they could otherwise.
As the glutes fatigue, you will often notice when lunging that people cease to rise with a vertically aligned torso - instead they start to lean forwards, straighten the legs, and then straighten the body up the top. It becomes a two-movement, hip-swaying lunge: legs then back. This serves no particular purpose - if you cannot keep the body vertical, then the glutes are done. Rest and repeat when you like, but if you push through when the muscles you are trying to train are fatigued and unresponsive, then you’re only training poor movement patterns. And I don’t give a damn how many calories you’re burning, athletic progression is about specificity, movement efficiency and the development of power. You don’t get that by compensating with your lower back, and burning calories has exactly zero relevance when it comes to athletic advancement.
As a little aside, the terms ‘weak’ and ‘strong’ are strictly to be used in a relative sense, free from judgment. A person may be weak or strong when compared to other people, and your glutes may be weak or strong when compared to your quads. Any person may have a well- or poorly-balanced musculature, but it doesn’t reveal anything about your character or worth, so y’know – whatevs, dude. Work on what you want to work on. I’ve been using the terms ‘relative’ and ‘absolute’ much more frequently in life – I find them quite useful. Your relative strength has to do with muscle balance and strength in relation to your own body, while your absolute strength has to do with the actual number of kilograms you can move. Hence, push-ups and lunges test your relative strength, while picking up a 20 pound dumbbell and lifting it for numbers tests your absolute strength. Maybe, for me, it’s just another way to strip away levels of judgement and prejudice. There are different types of strength and power. What’s meaningful for your progression?
So – if when you lower into the position, you feel a stretch in the hip-flexors and quads of the rear leg, you feel your knee joints are comfortable, you feel the hamstrings and glutes of the front leg working for balance, power and stability, you don’t feel your lower back pinching, you can keep your chest up without leaning forward, and you can press your heel and the inside edge of the ball of your foot into the ground, while lifting through the arch, if you can be aware of all this, you’re doing really well! Hooray! If you can, hold this bottom position for a heartbeat (experiencing the stretch and tension) before squeezing the glutes of your front leg and pressing back up to the top. Adjust your foot-positioning if need be.
When you reach the degree of strength, coordination and awareness that you can practice this movement for multiple repetitions without losing balance, we can start to talk about further progressions, which can be as easy as holding onto dumbbells, changing the height of the step, leading into small jumps with the front leg, or extending one arm up above your head.
More to come, dear readers, more to come.
But there’s no need to rush. Work within your capacity and challenge yourself as you like. Muscles adapt faster than ligaments, tendons and joints, so pay attention to your joints, pay attention to where you’re feeling the stretch and tension, and adjust as need be.

(Edit: 19 June 2014) Also, this is a great article, all about cueing the position of the knees, and how the foot, ankle and knee interact with each other through the shin bones. It contradicts much of what I have learned so far, but in a good way, and although it still leaves some questions unanswered, it's well worth reading, especially if you experience any foot/ankle/knee problems when squatting.
