When you’re pregnant, you get (often unsolicited) advice everywhere you go. When it comes to physical activity that advice variation can be insanely varied. From your in-laws telling you to not pick up a laundry basket to your friend PR’ing her snatch at 7 months pregnant. With so much advice out there we hope to clear up some questions about CrossFit during pregnancy.

We do know one thing: for uncomplicated pregnancies, exercise should be encouraged for those who are already physically active as well as those who have never worked out.

*Uncomplicated = no unexplained bleeding, no ruptured cervix, no triplets or quadruplets +, no pre-eclampsia, no placenta previa (after 28 weeks), no uncontrolled gestational diabetes or hypertension or thyroid issues, no recurrent pregnancy loss, no history of spontaneous preterm births, no malnutrition,  no eating disorder or any other complication. 

So what are the things we can and cannot do in CrossFit during pregnancy?

What Should I Lookout For?

First & foremost, there are a few things to watch out for, as these indicate your body is not ready for the exercise or intensity of the exercise you are performing:

  • Pain
  • Heaviness or dragging in or beneath vagina
  • Leaking urine or stool 
  • Coning / doming (oftentimes words used interchangeably, see image below)
diastasic recti

Pregnancy places significant stress on your pelvic floor and abdominal wall as your baby grows. Heaviness, leaking, and doming each occur when abdominal pressures are built higher than your muscles can handle.

Training through the above symptoms is you ignoring your body telling you it is being overstressed. When these signs are ignored it makes your postpartum recovery more difficult and drawn out.

Why? When those abdominal or pelvic floor muscles get so fatigued they can no longer do their jobs efficiently, then you’re no longer able to train them. If you’re not training the muscles, then they’re getting deconditioned. If they’re deconditioned, then just like any muscle, it will take longer and be harder to return to their prior state of fitness. 

So what could you do instead? 

  • Modify the number of repetitions you do to match your fatigue points
  • Modifying the volume of training you do. Instead of doing 5 RFT (rounds for time), you may do the same exercises but 3 rounds so you can focus on quality of movement through breathing & controlling your muscles. 
  • Modify the exercise. For example, instead of hanging from a pull-up do some banded pulldowns with a heavy band which still works your back with less strain of the abdomen

When you adjust your training properly you will walk the line between maintaining (and improving) fitness during your pregnancy without delaying your healing process postpartum.

First Trimester Considerations

During the first trimester we don’t expect to see many contraindications in CrossFit during pregnancy. The exception here typically becomes just listening to your body’s fatigue and nausea levels.

Second Trimester Considerations

With your growing baby (and your baby bump), modifying becomes more important in the second trimester.

You’ve spent a lot of time working on your barbell lift form and as your baby bump expands it can lead to altered paths. We believe that long term your fitness will be best if we don’t significantly alter your technique. So for most women we substitute barbell Olympic lifts for kettlebell and dumbbell variations.

During advanced CrossFit Gymnastics movements such as pull-ups, toes-to-bar, L-sits, muscle-ups, rope climbs, and hollow holds, we place a lot of tension on the abdominal muscles. We don’t want to create too much pressure to a point where they are no longer controlled (i.e. when you experience doming/coning/leaking/heaviness/dragging).

So what could you do instead? Plank variations (as long as you’re able to maintain control!), ring or banded rows, and lat pulldowns are great exercises which respect the abdominal tissues while challenging your extremities. 

The valsalva maneuver is when you hold your breath during heavy lifting. We do this to increase pressure and control around our midline and spine to be able to lift more. As I’m sure you’ve caught by now, we know that pregnancy alone increases pressure on the abdomen and pelvic floor, constantly. The valsalva then, adds undue pressure in those areas, which again may slow your postpartum recovery.

What can you do instead? Use the “blow as you go” technique: 

A) Inhale during the descent of a lift and 

B) Exhale as you rise. 

This allows for the normal ebb & flow of the abdominal and pelvic floor muscles, limiting the extra pressure while maximizing your strength benefits. 

Anything else? 

Speaking of added pressure, activities like running, box jumps, burpee jumps, double unders all significantly increase the downward pressure into your already-taxed pelvic floor. Consider slowly regressing the intensity of these activities to lessen the risks of incontinence postpartum.

Lastly, it is vital for your & your baby’s wellbeing to avoid activities which may result in a fall or traumatic injury. This includes: handstands, rope climbs, muscle ups, & ultimately any activity in which you question its safety. 

Third Trimester Considerations

While most exercise modifications happen in the second trimester, the largest changes in the 3rd and final trimester both in the (A) weights you lift and (B) range of motion you lift through. Using the deadlift as an example, as your baby bump grows it may become increasingly difficult to perform this movement with a narrow stance. Because of this, many women will adopt a sumo stance – positioning the feet wider to move the legs out of the way of the belly. (See below image.) The squat is another example: you may have difficulty getting to or out of a full-depth squat and may choose to squat to a box or med ball.
