In the 1st trimester, there are only a few things to be careful of. For most women, it is ok to lie on the back until 12 weeks, so you can still do sit ups. If you were already doing CrossFit before you became pregnant, you should still be able to perform most exercises.
However, it is recommended that you reduce weights on Olympic lifts and exercises such as kettlebell swings. 40-50% of your max seems to work for most women.Your blood volume increases when you become pregnant, so trying to keep your heart rate at 140 bpm when exercising doesn’t allow you to do much.
Rather than focusing on heart rate, pay attention to your breathing. You should still be able to talk while working out. This is a time for maintenance not intensity. Don’t work out until the point of exhaustion and don’t get over-heated.
Chose a workout space close to the window or fan, because you don’t want your core temperature to get too high.Make sure you rest between rounds or exercises as you need to, and sip water before, during and after your workout; and as always, check with your doctor that you have no considerations regarding continued exercise.
If you were not already doing CrossFit prior to becoming pregnant, it is not recommended that you commence a “vigorous” exercise programme during pregnancy.
Working with a Coach one-on-one may be a good choice for you, or participating in CrossFit Auckland Women and scaling as necessary.
In the 2nd trimester, more changes in your body begin to occur, and workouts need to be adjusted accordingly. First, no more exercises that require lying on the back. The uterus weighs enough to cut off blood supply to the baby, so alternate core exercises will need to be implemented.
Do push-ups until you can’t any more, then move to incline and then wall push-ups. You’ll still feel your abs working! Kipping pull-ups will probably start to become uncomfortable so switching to ring rows is one alternative.This would also be the time to switch from box jumps to step ups.
Your joints are looser due to the relaxin hormone, so ballistic exercises are best adapted. Olympic lifting should be modified to minimal at this point. Some women are still comfortable doing the lifts with light weight, but this is not for everyone.
Front squat, back squat and overhead squat with an empty bar or even wooden dowel will still be enough work, but you don’t want to squat below 90 degrees.
Shoulder press and push press are excellent at working the upper body. Rowing, walking and good mornings are all exercises that should feel comfortable to you, and help keep your hips and back strong!
Remember to check with your doctor that you have no considerations regarding continued exercise.
In the 3rd trimester, there are a lot of changes. Your growing belly will be in your way for a lot of exercises. If you were still able to do push-ups in your 2ndtrimester, you will probably have to go to the wall now.
When you squat, it should only be bodyweight squats and not past 90 degrees. Push press and shoulder press are still good exercises, but don’t go too heavy.If you can still row, go for it. It works a lot of muscles. Keep walking, and doing good mornings, and do step-ups on either the 20” or 12” box, whichever your body will allow.
Do farmer’s walk, lunges (not too deep) and ring rows. Don’t forget to rest, sip water and make sure your doctor ok’s your exercise programme. Many exercising women feel comfortable to continue modified exercise right through to birth – always listen to your body and do what feels right for you!
In the post-partum phase, you can begin to get back to your normal workouts. The main things to watch for are ballistic movements; take care of your ligaments and listening to your body.
Don’t do anything that doesn’t feel good.
Increase weight and intensity slowly while your body adjusts to not being pregnant. You will be tired initially, caring for a newborn. Give yourself a little time to get back into it, but above all, keep moving!You will get the energy you need to keep up with your baby.
Working out will help you get your body back, and help you feel like you are doing something for yourself. It’s good for the mind, good for the body. Make sure your doctor approves of your post-natal exercise programme.
Most important is that you listen to your body and discontinue doing anything that simply ‘doesn’t feel right’ for you.
