Prenatal Fitness Tracker

Trimester context and how workout type changes week by week

The tracker asks for Pregnancy Week as the baseline context because appropriate exercise varies significantly across the trimesters. In the first trimester, most pre-pregnancy activities can continue with standard precautions. In the second trimester, impact modifications and positioning changes begin — supine exercises should be avoided from around 16 to 20 weeks. In the third trimester, workout type, intensity, and duration often need further adjustment based on size, pelvic floor stress, and cardiovascular demand.

Workout Type options include walking, swimming, prenatal yoga, strength training, cycling, running, pilates, and other categories. Tracking the type week by week shows your care team whether you are progressively modifying as the pregnancy advances or maintaining an intensity that may need adjustment. A consistent running practice at 32 weeks may be perfectly appropriate for one person and warrant modification discussion for another — your provider makes that determination based on your full picture.

The Pre-Pregnancy Fitness Level field calibrates expectations. Someone who was marathon training before pregnancy has a different fitness context for the numbers they report than someone who was sedentary. The tracker accounts for this in its output.

Intensity level and the exercise ceiling during pregnancy

Intensity on a 1-to-10 scale lets you self-rate exercise exertion. General guidance for most pregnant people suggests staying below an intensity level where you cannot hold a conversation — roughly equivalent to a 6 to 7 out of 10 exertion. High-intensity interval training, breath-holding exercises, and very high-impact activities typically require modification or cessation by the second or third trimester.

Tracking intensity alongside energy level shows your care team whether you are self-regulating appropriately or whether there is a disconnect between your effort and how you are feeling. Someone who rates intensity at 8 but energy at 3 on the same day is potentially overexerting in a context where the body is signaling inadequate recovery resources. That pattern is worth discussing with your OB-GYN or certified prenatal fitness specialist.

The goal is to maintain fitness and manage pregnancy symptoms, not to push performance. Let the intensity field be honest.

Pelvic pressure during exercise: when to modify and when to stop

Pelvic Pressure During Exercise on a 0-to-10 scale is one of the most important safety fields in this tracker. Pelvic pressure during exercise — a feeling of heaviness or downward pressure in the pelvic region — is a signal to reduce intensity or stop. It can indicate that the activity is creating more intra-abdominal pressure than the pelvic floor can currently manage, particularly in the second and third trimesters.

A pelvic pressure rating of 4 or above during exercise is a signal to modify the specific activity immediately and discuss it with your pelvic floor PT or OB-GYN at your next opportunity. Continuing high-impact or high-intensity exercise through significant pelvic pressure can contribute to pelvic floor dysfunction. The tracker makes this symptom visible in the weekly record rather than having it go unnoticed or unreported.

Log what you actually experience, not what you hope is happening.

Round ligament pain: tracking a common third-trimester experience

Round Ligament Pain on a 0-to-10 scale captures a specific pregnancy discomfort: sharp, stabbing pain typically on the lower abdomen or groin, often triggered by sudden movements, exercise, rolling over in bed, or coughing. It is usually harmless but can be sharp enough to cause hesitation around movement.

Tracking its severity alongside workout type and intensity helps you identify which specific activities trigger it and at what intensity threshold. Many people discover that specific movements — quick changes of direction, high-impact activities, or core exercises that stretch the ligaments — are the primary triggers, and modifying those activities often reduces the symptom significantly without eliminating exercise entirely.

If round ligament pain is severe, one-sided and persistent, or accompanied by any other unusual symptoms, contact your provider to rule out other causes. The tracker records the symptom and your provider evaluates it.

OB clearance and the role of professional guidance

The OB Clearance for Exercise field records whether your provider has reviewed and approved your current exercise routine. For people with certain pregnancy complications — placenta previa, preterm labor risk, incompetent cervix, pregnancy-induced hypertension, or significant anemia — exercise may be restricted or require specific modifications that go beyond general guidelines.

If you have not discussed your exercise routine with your provider, the first step before increasing exercise during pregnancy is that conversation. This tracker assumes OB clearance is in place or being pursued. It does not determine safe exercise levels for individual pregnancies. Log it free — your trimester-by-trimester exercise record belongs in your prenatal file, not scattered across memory.

Important: this is a self-tracking tool, not medical advice

This tracker is a self-monitoring tool, not a diagnostic device. The information you enter and the scores it produces are for personal awareness and for sharing with your clinician — they are not a substitute for professional medical evaluation, diagnosis, or treatment. Do not change medication, dose, or treatment plan based on this tool. If you experience symptoms that concern you, contact your clinician; for emergencies in the US, call 911 or your local emergency number.

Prenatal Fitness Tracker vs. the alternatives

How to use it

1. Enter your Pregnancy Week and the number of Workouts This Week for the current period.
2. Log Workout Duration Today in minutes and select the Workout Type you completed.
3. Rate Intensity from 1 to 10 and your Energy Level from 1 to 10 for the session.
4. Score Pelvic Pressure During Exercise from 0 to 10 based on any pelvic heaviness or pressure felt during the session.
5. Rate Round Ligament Pain from 0 to 10 and select your Pre-Pregnancy Fitness Level and OB Clearance status.
6. Print the weekly exercise summary to bring to your prenatal appointments and review any pelvic pressure patterns with your pelvic floor PT.

Who it's for

• Runner adjusting training through the second trimester — A runner who was training at 40 miles per week before pregnancy tracks intensity, pelvic pressure, and round ligament pain as they modify their training, using the data to discuss appropriate transition to lower-impact options with their OB-GYN.
• First-time exerciser using pregnancy as motivation — Someone new to regular exercise starts walking and prenatal yoga during pregnancy, tracks weekly workout count and energy levels, and brings the progress record to each prenatal visit as a positive report.
• Person developing pelvic pressure symptoms — A person who starts noticing pelvic pressure scores of 5 to 6 during strength training at 28 weeks tracks the symptom across three consecutive sessions, prints the record, and requests a pelvic floor PT referral from their midwife.
• Person on modified exercise restriction — Someone told to reduce exercise at 30 weeks due to blood pressure concerns uses the tracker to document their modified routine and demonstrate compliance with the restriction to their OB-GYN.

Key terms

Round ligament pain

Sharp, brief pain in the lower abdomen or groin caused by stretching of the round ligaments as the uterus grows. Common in the second and third trimesters and often triggered by sudden movement or exercise.

Pelvic floor

The group of muscles at the base of the pelvis that support the pelvic organs. Exercise-induced pelvic pressure during pregnancy can indicate the pelvic floor is under load it cannot currently manage and may warrant modification.

Prenatal exercise intensity

The exertion level during pregnancy exercise, typically recommended to stay in a moderate range where conversation is possible. The talk test is a practical proxy for keeping intensity within safe limits.

OB clearance

Explicit approval from your obstetric care provider to exercise during pregnancy. Essential for anyone with pregnancy complications or high-risk factors before beginning or continuing an exercise program.
