Standard crunches or sit-ups are often not recommended for postpartum women, especially when we know a diastasis recti or DRA is present. This is because the way<\/em> a crunch is usually performed<\/em> may have the effect of increasing intra-abdominal pressure, pushing your organs outwards against or through the gap, and\/or downwards onto the pelvic floor – directions you really don’t want your organs forcefully heading. You can actually see<\/em> what you’re training your abs to do if you look straight down as you curl up: a cone shape, bread-loaf shape or a pregnant looking belly\u2026 these may be signs of diastasis recti<\/a>, or that your core is not functioning optimally\u2026 and not the effect you’re working out to achieve. See animated image >>><\/p>\n\n\n\n

So postpartum exercise specialists and Women’s Health Physiotherapists will often recommend against crunches until the core musculature (including the pelvic floor) is restored and strong enough to withstand the movement.<\/p>\n\n\n\n

BUT\u2026 and there is a but<\/em> here\u2026 supine spinal flexion (the forward curl-up motion from lying on your back) engages and shortens the rectus abdominis muscle (a good thing). The rectus is the vertical, ‘six-pack’ abdominal muscle, the exact same superficial abdominal muscle that has separated from its midline connective tissue. A diastasis compromises all your ab muscles, both laterally as the gap widens from side to side, as well as lengthways along the stretched and weakened rectus. So diastasis recti exercises<\/a> to shorten it, if performed correctly, is a good thing<\/strong>.<\/p>\n\n\n\n

The other but<\/em> is that spinal flexion (bending forward, whether lying on your back or in any other position) is a perfectly useful human, functional movement. Sometimes, you want or need to curl your body or bend forward. Sometimes against resistance. Maybe not repetitively, or excessively, but you might want to curl all the same.<\/p>\n\n\n\n

So if it’s both potentially beneficial in shortening the stretched-out rectus, and<\/em> it’s essentially functional, why do we tell you not to do it?<\/p>\n\n\n\n

Crunches and diastasis recti<\/h2>\n\n\n\n
  1. Before you train the abdominal muscles in this way, you want to ensure the deeper abdominal muscles are actually recruiting (meaning\u2026 ‘kicking in’ and working): the Transverse, the Inferior Obliques and the Exterior Obliques all work together, along with the muscles of your pelvic floor. This vital phase of mind-to-muscle reconnection, of learning to recruit and engage the right muscles, first in isolation and then as a unit, must come first. That’s what MUTU System does.<\/li>
  2. Also, there are common crunching technique ‘habits’ that could make a diastasis or weak pelvic floor worse, not better. Often crunches are performed whilst sucking in, or holding your breath, causing your stomach to pooch or bulge out and your organs to bear down on your pelvic floor. Often the hip flexors and lower back are taking most of the strain, and the targeted muscles, the rectus abdominis as well as the deep transverse abdominis muscle, are not recruiting at all, whilst the diastasis gap could be widening further.<\/li><\/ol>\n\n\n\n

    So unless so you are being guided to gauge whether midline tension of the core musculature is being maintained, and pelvic floor function is controlled and protected, you could do more harm than good. It is preferable and much safer to find alternatives with techniques and patterns which have less potential to harm.<\/p>\n\n\n\n

    I spent time recently in LA [2015] having\u00a0been asked to consult for an exercise instructor training company on adapting workouts for pregnancy and postpartum. As we played and experimented with various adapted ‘crunch’ movements, we decided it was time to put this information out there! We both are often heard recommending against crunches, when giving general<\/em>, online advice <\/em>where careful personal supervision isn’t possible. By the very nature of the MUTU System online program<\/a> and blog, we simply cannot be ‘hands-on’ enough to be sure you’re getting it right and therefore caution prevails.<\/p>\n\n\n\n

    I also wanted to write this because often a Women’s Health Physiotherapist<\/a> will specifically prescribe a variation of a curl movement at the appropriate stage of her client’s recovery, and I know (because you regularly write to me about it) that you worry that ‘all crunches are bad’. Be mindful that your therapist or Physio will be carefully monitoring and cue-ing breathing and technique to ensure the right muscles are doing the work and full benefits are being achieved. Your stage of restoration is appropriate, you’re recruiting the right muscles\u2026<\/p>\n\n\n\n

    \u2026The movement is not a bad movement. <\/strong>You just need to be sure you’re getting it right, and that your body is ready for it.<\/p>\n\n\n\n

    So how do you know if you’re doing it right?<\/h2>\n\n\n\n

    First follow some foundation training (like MUTU or with a specialist Physio) around engaging deeper abdominal muscles, before progressing to full crunches. Then:<\/p>\n\n\n\n

    Are you able to isolate and find your core muscles?<\/strong><\/h3>\n\n\n\n

    Try this from lying on your back with knees bent up and feet flat on the floor. Place your hands on your \u2018hip bones\u2019 \u2013 the bony corners that jut out at the front of your pelvis on each side). Move your fingers slightly inwards and downwards from there, where it’s soft. Exhale as you gently draw your abs inwards, whilst engaging your pelvic floor muscles. Imagine you’re drawing a tampon further up inside you. When you engage your TVA and PFM, you will feel a tensing of the broad flat muscle under the pads of your fingers. It should be tensing downwards, towards your body, not bulging, pushing or straining outwards. If your stomach pooches or pushes away, if you\u2019re holding your breath or the movement is forceful, then you\u2019re working the outer abdominal muscles and TVA isn\u2019t doing its thing.<\/p>\n\n\n\n

    Your body’s clear signals you should back up a little before progressing further<\/strong><\/h3>\n\n\n\n

    Watch for these red flags when attempting to engage your core without strain first, then especially when performing any abdominal exercise. If you are experiencing (feeling and\/or seeing) any of these symptoms when intra abdominal pressure is increased, you’re not getting it right, and you’re doing more harm than good. Back up. You’re not ready yet.<\/p>\n\n\n\n
