You wake up in the morning, stretch – and suddenly you notice: The heavy fatigue of the first weeks is gone. Your belly gently curves, but you feel more powerful than you thought. At the same time, you might be wondering: Can I really exercise now? What is safe for my baby? The good news: Your body is ready for movement at 15 weeks pregnant – and your baby benefits from it.

Why Exercise is So Important at 15 Weeks Pregnant

In the middle of the second trimester, your body is rapidly changing: Your blood volume increases, your joints become looser due to hormones, and your center of gravity shifts. Regular exercise helps you cope with these changes better – it strengthens your muscles, stabilizes your circulation, and prevents typical complaints like back pain or water retention.

Studies show: Pregnant individuals who engage in at least 2.5 hours of moderate-intensity exercise per week often experience an easier delivery, less gestational diabetes, and feel more emotionally balanced. Moderate intensity means: You can still talk, but you are slightly out of breath – like during a brisk walk.

What Happens in Your Body?

  • Circulation: Exercise promotes blood flow and helps prevent dizziness and varicose veins
  • Back: Targeted exercises relieve the spine, which is under increased strain from the growing belly
  • Pelvic Floor: Training this muscle group prepares you for childbirth and aids in postpartum recovery
  • Mind: Endorphins boost your mood and reduce pregnancy-related anxiety

The Best Forms of Exercise for the 15th Week of Pregnancy

Not every sport is suitable right now – but the options are broader than many think. Ideal activities are those that gently challenge your entire body without risk of falling or abrupt movements.

Recommended Sports

  • Walking: Perfect for every day, prevents edema, easy to integrate into daily life – just 30 minutes daily makes a difference
  • Swimming: Relieves joints and back through buoyancy in water, trains endurance without overheating, especially beneficial for heavy legs
  • Pregnancy Yoga: Strengthens pelvic floor and back, promotes conscious breathing for birth, reduces stress and tension
  • Light Weight Training: With adjusted weights (e.g. 1-2 kg dumbbells), you strengthen arms, shoulders, and legs – important for later carrying your baby
  • Cycling: A joint-friendly endurance option on a stationary bike or flat paths (be aware of fall risks on uneven terrain!)

Additionally, you should now regularly incorporate pelvic floor training: Tighten the muscles as if you were stopping the flow of urine, hold for 5 seconds, relax – repeat this 10 times, several times a day.

What You Should Definitely Avoid Now

As beneficial as exercise is – some activities carry unnecessary risks. Avoid sports with a high risk of falling or collision, as your joints are looser and more prone to injury due to the hormone relaxin.

  • Contact Sports: Soccer, basketball, martial arts – bumps to the belly are off-limits
  • Horse Riding, Skiing, Inline Skating: The risk of falling is too high
  • Extreme Sports: Climbing, bungee jumping, diving – pressure equalization and oxygen supply can be problematic
  • Overheating: Hot yoga or training in temperatures above 30°C puts too much strain on the circulation
  • Abdominal Exercises: Classic sit-ups may exacerbate diastasis recti (the gap between the abdominal muscles)

Also, make sure to regularly interrupt long sitting periods – stand up every hour, stretch, and take a few steps. This promotes circulation and helps prevent thrombosis.

Your Weekly Plan: How to Incorporate 2.5 Hours of Movement

The recommendation of at least 2.5 hours per week sounds like a lot – but it's easier to implement than you think. Spread the activity over small segments that fit into your daily routine.

Sample Weekly Plan

  • Monday: 30 min. morning walk + 10 min. pelvic floor training
  • Tuesday: 20 min. pregnancy yoga (YouTube video) + stairs instead of elevator
  • Wednesday: 30 min. swimming or aqua fitness
  • Thursday: 15 min. light weight training (arms, shoulders) + 15 min. walk
  • Friday: Rest day or gentle stretching (10 min.)
  • Saturday: 40 min. bike ride or longer walk with partner
  • Sunday: 20 min. yoga + relaxation exercises

Tip: Combine movement with social moments – meet a friend for a walk, or do yoga together with your partner. This increases motivation and makes it more enjoyable.

Warning Signs: When You Should Pause Immediately

Your body gives you clear signals when something is wrong. Pay attention to these warning signs and pause immediately if you notice any of the following symptoms:

  • Vaginal bleeding or fluid loss
  • Severe headaches or persistent dizziness
  • Pain in the abdomen, chest, or back
  • Persistent shortness of breath or racing heart
  • Contractions or hardening of the abdomen
  • Sudden swelling in the face, hands, or feet

In these cases, contact your midwife or doctor immediately. Better to be cautious than negligent.

The Rule of Thumb for Safe Intensity

The Talk Test is your best companion: If you can still have a normal conversation while exercising without gasping for air, the intensity is just right. As soon as you can only speak in short sentences, slow down.

Frequently Asked Questions About Exercise at 15 Weeks Pregnant

Can I continue jogging if I did before pregnancy?
Yes, if your body is used to it and you feel comfortable. However, reduce the pace, ensure proper cushioning in your shoes, and switch to walking if you feel unwell. Many women find bouncing uncomfortable starting in the second trimester.

How do I know if I'm overtraining?
Persistent fatigue, sleep problems, frequent headaches, or the feeling that you can't recover are signs of overtraining. Your body needs more recovery time now – give yourself plenty of breaks.

Is it okay to lift weights?
Light weight training with 1-3 kg is fine and even recommended. However, avoid heavy lifting (over 5-7 kg), breath-holding exercises, and any exercises lying on your back after 20 weeks. Focus on functional movements like squats or standing arm exercises.

What if I was inactive before pregnancy?
Perfect – now is the ideal time to start gently! Begin with 10-15 minutes of walking daily and gradually increase. Your body will adapt, and any movement is better than none.

Do I need special sportswear?
A well-fitting sports bra with wide straps is important as your breasts grow. Comfortable, breathable clothing and well-cushioned shoes make exercise more enjoyable – but expensive maternity sportswear is not strictly necessary.

Your Body, Your Pace – Trust Yourself

The 15th week of pregnancy is a wonderful time to reconnect with your body. Movement is not a must, but a gift to you and your baby – it strengthens both of you, makes you more resilient, and provides valuable moments of connection with your body.

Don't let perfect workout plans or Instagram pictures pressure you. Your pace is the right pace. Whether you walk for half an hour daily or swim three times a week – every form of movement counts. Listen to your body, celebrate small achievements, and enjoy the good feeling that exercise brings you.

You're doing great – and so is your body. Trust it, it knows exactly what it needs.
