I'm pregnant! When & why do I need to modify my exercise?
Pregnancy is your time to embrace a maintenance phase - a time to focus on sustaining your strength and energy, rather than chasing personal bests or trying something new. In this blog we discuss why modifying your exercise as you progress through your pregnancy is important and when you need to start thinking about making those modifications. We hope you find it helpful!
But when do you start to modify your exercise?
You can continue your normal exercise routine up until 16 weeks pregnant. At 16 weeks it is recommended that you take pregnancy modifications in specific exercises. However, this is just a general guideline and could be earlier depending on your pregnancy, what number pregnancy or your general fitness and wellbeing. Everyone is different, some women feel really sick and feel they need to modify sooner, other women feel strong and like they can continue as they have been for that first 16 weeks - everyone is different.
Here’s why you should modify your exercise:
To support your pelvic floor
Imagine your Pelvic Floor is a hammock, when more weight is added to the hammock it begins to drop and stretch. As your bump grows throughout your pregnancy, more and more weight is loaded on the pelvic floor muscles. Pregnancy makes these muscles more elastic and mobile, particularly around the pelvic organs (bladder, uterus and rectum). A weak pelvic floor can lead to urine leakage, incontinence, lower back pain, difficulty emptying the bladder, painful sex or a prolapse. While you’re exercising, keep checking into your pelvic floor and exhale on the hardest part to avoid downward pressure.
2. To protect your core
As your bump grows the connective tissue (linear alba) begins to stretch. Direct core exercises working your six pack abs (rectus abdominus) and loaded twisting movements put too much pressure on the connective tissue which can enhance this risk of abdominal separation. While abdominal separation is a normal part of pregnancy, we do want to reduce any additional loading and do what we can to minimise the risk. This doesn’t mean you shouldn’t continue core exercises they just need to be pregnancy safe.
3. To keep you safe and strong
During pregnancy, your body produces relaxin, a hormone that increases ligament and joint elasticity to prepare for childbirth. While helpful, this also makes joints less stable, raising the risk of injuries like sprains or strains. Coupled with posture changes, a shifting center of gravity, balance and coordination are also affected. At She Moves our belief is that it’s best to stick to Low Impact exercise, avoid overstretching and focus on stability.
We also recommended that you avoid lying flat on your back due to potential pressure on major blood vessels. While this can be a controversial topic in the fitness world at She Moves we will always lean on the side of caution with this. When lying flat on your back, the growing uterus can compress the inferior vena cava - a large vein that carries blood back to the heart from the lower body. This can reduce blood flow, potentially causing dizziness, shortness of breath, or a drop in blood pressure, there is also a small possibility that it may also reduce blood flow to the baby. We like to opt for side-lying positions or an incline to keep blood flowing and feel your best!
Remember, this time is all about maintaining strength, supporting your body through the aches and pains of pregnancy and keeping mobile - not pushing for PB's! You’re already achieving something incredible by growing a tiny human! Embrace this maintenance phase, make those small exercise adjustments, and focus on feeling good. Your body is doing amazing work - celebrate it!
