The third trimester program

Gently prepare the pelvis and breathing for birth

The third trimester is the home stretch. The belly is large, the center of gravity has shifted, there is less energy, the ligaments are at their softest. Classic "workouts" give way to preparation for birth. The goal of this phase is not to "keep your shape" but to teach the body to breathe, to relax the pelvic floor, to take birth positions, to manage load through contractions. These are skills you cannot learn in the middle of birth – they need to be trained in advance. The program is built around three blocks: breathing (including techniques for contractions), pelvic mobility (the exercise ball, leans, rocking), gentle strength work for the glutes and legs (they will work during pushing). All of it happens at a calm tempo, with short 30–40 minute sessions. The intensity is lowered – the main thing is not to get tired, but to go into birth rested. If swelling, dizziness or shortness of breath at rest appear, workouts are paused and we see a doctor. After week 37 the program simplifies even further – only breathing, walking and rocking remain. The body is ready for birth, and our job is not to get in the way.

Gently prepare the pelvis and breathing for birth

Core principles

What we do
  • Gentle "cat-cow" on all fours
  • Rocking on an exercise ball daily
  • Wall half-squats, short holds
  • Hip opening – half-lotus, "figure 4"
  • Diaphragmatic breathing + Kegels + reverse Kegels
  • Walking 30 minutes a day at a comfortable pace
  • Swimming, if there are no contraindications
What we avoid
  • Lying on your back longer than 5 minutes
  • Crunches, the classic plank
  • Jumping, running, impact load
  • Raising the arms overhead with weight
  • A quick change of position – a risk of dizziness
  • Breath-holding (the Valsalva maneuver)

Exercises

The full set of exercises for this phase. Each one comes with an illustration, sets, and steps. Do them under a trainer’s supervision or after agreeing it with your doctor.

№ 01

Cat-cow

2 × 10
  1. On all fours, palms under the shoulders, knees under the hip joints. The back is neutral
  2. Exhale – round the back, the head gently drops down, the pelvis tucks under
  3. Inhale – make a slight arch in the thoracic spine, the head rises forward and up
Important

Builds the skill of a neutral spine and teaches you to move the back without engaging the lower back. Safe before and during pregnancy.

№ 02

Rocking on an exercise ball

daily · 10 min
  1. Sitting on the exercise ball, feet on the floor, shoulder-width apart
  2. Rock gently back and forth and in circles
  3. Breathing free, the shoulders down
Important

If it feels unsteady – have a wall or a chair nearby for support.

№ 03

Wall half-squat

3 × 20–30 sec
  1. The back pressed to the wall, feet hip-width apart
  2. Sit into a half-squat (the angle at the knees is not sharp)
  3. Hold at a comfortable level
Important

Do not lower below your comfort level. The knees do not go past the toes.

№ 04

Deep squat with support

3 × 8
  1. Holding a chair or the wall, feet wider than the shoulders
  2. Slowly lower into a comfortable squat, the torso upright
  3. A deep inhale into the perineum, exhale – rise
Important

Only if there is no symphysitis. If the pubic area hurts – skip it.

№ 05

Side stretch on the exercise ball

2 × 6 per side
  1. Sitting on the exercise ball, one hand resting on the thigh
  2. Raise the opposite arm and lean to the side
  3. Hold on the inhale, return on the exhale
Important

No sharp leans. The pelvis stays level.

№ 06

Pelvic floor lying on your side

2 × 5 min
  1. On your side, a pillow between the knees, a palm on the belly
  2. Inhale – the belly expands, the perineum relaxes
  3. Exhale – a gentle squeeze of the pelvic floor
Important

The main thing is relaxation. Without an over-strong squeeze.

№ 07

Hip opener

2 × 1 min
  1. Sit on the floor cross-legged, hands on the knees. Feel that you are sitting on the two sitting bones at the bottom of the pelvis – to do this, roll the pelvis slightly forward
  2. Tilt the torso slightly forward, keeping the lower back straight
  3. Breathe calmly, with each exhale gently relaxing the inner thighs
Important

Good hip mobility makes birth easier – it is worth building up in advance.

№ 08

Hug the exercise ball

2 × 2 min
  1. On your knees, the exercise ball in front of you
  2. Wrap your arms around the ball, the torso relaxed over the top
  3. Breathing free, the weight on the ball
Important

A resting pose. If your head spins – sit down.

№ 09

Figure 4 lying down

2 × 30 sec per side
  1. Lying on your back with the head end raised, one leg bent
  2. Place the ankle of the other leg on the thigh of the bent leg
  3. Gently draw the thigh toward you, a stretch in the glute
Important

No longer than 5 minutes on your back. If you go numb – switch to your side right away.

№ 10

Standing march

3 × 20 steps
  1. Standing tall, hands on the hips or holding support
  2. Lift the knees one at a time to a comfortable height
  3. A calm tempo, breathing free
Important

With dizziness or pubic pain – stop.

№ 11

Breathing for birth

daily · 5 min
  1. Semi-seated on the exercise ball or with support, eyes closed
  2. A slow inhale through the nose into the belly – 4 counts
  3. A long exhale through the mouth past relaxed lips – 6–8 counts
Important

The key practice. It trains breathing through contractions.

№ 12

Knee push-ups

3 × 10–12
  1. Get on all fours, palms under the shoulders, knees on the floor. The back straight from the knees to the crown of the head
  2. Exhale – bend the elbows, lower the chest toward the floor. The elbows track along the body
  3. Inhale – push off the floor and return to the starting position
Important

Strengthens the chest muscles and triceps – it will help you hold your posture as the belly grows and carry your baby in your arms. Keep the back straight, do not sag in the lower back.

Frequently asked questions

When should I stop training before birth?

If the pregnancy is without complications – we train right up to birth.

The program at weeks 36–40 comes down to gentle activity:

  • Diaphragmatic breathing
  • Walking
  • Rocking on the exercise ball

This is not "training", it is activity that helps birth start and go more easily.

The only reason to stopYour doctor’s instruction.

Why relax the pelvic floor instead of strengthening it?

In birth the pelvic floor must be able to open – the baby will pass through it.

If we trained only the squeeze (Kegels without reverse Kegels), the pelvic floor becomes stiff and gets in the way of birth.

In the third trimester the work goes toward relaxation:

  • Reverse Kegel
  • Diaphragmatic breathing
  • Positions for opening up
Can I keep swimming in the third trimester?

If the pool is cleared by your doctor and there have been no complications – yes. Water takes the load off the back and joints, it is a relief.

What we avoid:

  • Jumping into the water
  • Breath-holding with straining
  • Overheating – not warm but cool water

Before weeks 38–39 some doctors limit the pool – we agree it.

What to do with pelvic pain (symphysitis) in the third trimester?

The third trimester calls for even gentler work.

Completely excluded:

  • Lunges
  • Single-leg raises
  • Any asymmetrical movements

What stays:

  • Squats with support
  • A two-leg glute bridge
  • Breathing
  • Spine mobilization
