So many songs have been written about the shape of a woman’s derriere we can be reminded fairly frequently that having some “junk in your trunk” is a good way to go. Whether your butt is big or small the most important thing is that the muscles within work really well as those muscles are pretty central to everything else that happens in the body. As a Mum the tendency is for our butt muscles to sag (let’s face it, everything else is!!) and “Mum Bum” becomes an actual reality, often accompanied by low back pain, pelvic floor weakness and posture changes through the rest of the body. Now I don’t care what your butt or mine looks like, what I care about is that the flat look indicates underused muscles and when your buttocks are underused your whole system is not working cohesively - your buttocks are 3 set of gluteal muscles, plus a number of deep hip rotators in the pelvis most recognisably, collectively called your “glutes” and they attach in and across the pelvis and out to the hip joint, also connecting with the fascia (connective tissue) of the quad, hamstring and hip flexor muscles and upwards they connect with the fascia of the lower back, core system and large shoulder organising/moving muscles of the lats. Plus very importantly when in comes to the movement Mums do and need to do on the daily, the glutes/deep hip rotators are completely connected with the pelvic floor - tight glutes = tight pelvic floor / weak glutes = weak pelvic floor. In general terms we know that all muscles in the body are connected but the glutes/buttock muscles drive movement up into the trunk and upper body and down through the hip, knee and into your ankle. So if you have a weak ankle that often rolls, look to strengthen the glutes, and if you have a clunky, hard to strengthen shoulder, look to work on exercises that strengthen both the glutes and shoulders together keeping in mind the fascial connection between the 2 areas.
When it comes to the pelvic floor and the glutes connection, there are 3 things you can consider:
How do you stand? The standard playground posture for Mums is hips swayed forwards, knees locked back and ribcage dropped back and down - when you’re tired and this is your 4000th trip to the park that week you go into energy saving mode which means hanging off your hips. The problem is to do this posture your glutes stay squeezed on all the time and they are not those sorts of muscles, they don’t like being switched on all the time so they get weakened by holding that position. When we stand with hips pressed forwards it also means the pelvic floor is locked on and unable to relax or contract.
How you use your glutes. As I’ve said above, the most important thing with the glutes is whether you are “switching them on and off”. Your glute muscles work best - and that means support your body and help it function well - when they go from some stretch to some contraction. To really wake the glutes up we need to stretch them in all directions they can go: twist, lengthen and flex, and then contract them in all ways. During strengthening exercises and movements we need to set the body up so that the pelvis is in a “neutral” position to be able to help the glutes lengthen and then work and we work the whole buttock muscle group in 3 dimensions as frequently as possible - think of the actions football and rugby players do around a pitch: side to side, sprinting fast, jogging slow, one leg standing, jumping and diving. I’m not saying that’s the only way to get good working glutes, but if you only work your muscles by going forwards to stand/sit, walk, occasionally jog and also stand with poor posture, your glutes are not going to be working optimally.
Glutes = pelvic floor. If you go to squat, sit on a chair or the toilet, walk up stairs, bend down to load the dishwasher, pick up toys from the floor, or go to pick your kids up you are using your glutes/pelvic floor over and over again. As we now know from all the above, we want our glutes to work well when we do use them so that means going through the squat movement with a fairly “neutral” spine, hinging at the hip joint instead of tucking the pelvis under (which would be the pelvis moving rather than the hip joint) and then lengthening through the back of the legs and glutes while you bend down/squat/sit which gets the glutes/pelvic floor in the right place to work strongly as you stand up. This is especially important if you are holding a load - a large, screaming toddler for example - as you don’t want your pelvic floor to be in a weak position causing leaking, or for it to tighten up too much as a reaction to poor patterning so while the pressure builds up in your abdominal cavity it presses down on your pelvic floor causing you to be susceptible to prolapse.
If you have low back pain, can feel tightness or weakness in your pelvic floor, or get aches and pains in your hips, knees and feet, making glute strengthening (with the right form) a priority will be a major part of your rehab, preferably under guidance.
