Exercise During Your Period: What to Do and What to Skip

"Can I train during my period?" is the question I hear most from my female clients. The answer: absolutely yes. In fact, skipping exercise entirely during your period often makes symptoms worse, not better.

But - and this is the important part - your body is not the same throughout your menstrual cycle. Hormonal fluctuations across the roughly 28-day cycle affect your energy, strength, pain tolerance, recovery, and even injury risk. Training intelligently with your cycle, not against it, is how you get the best results.

The Menstrual Cycle: A Quick Overview

Menstrual Phase (Days 1-5)

Your period. Both oestrogen and progesterone are at their lowest. Energy may be low, especially on days 1-2. Cramps, bloating, and fatigue are common.

Follicular Phase (Days 1-14)

Overlapping with menstruation and extending beyond it. Oestrogen gradually rises, peaking just before ovulation. You generally feel increasingly energetic, strong, and motivated through this phase. Pain tolerance is higher. This is your power phase.

Ovulation (Around Day 14)

Oestrogen peaks. Testosterone has a small spike. You're likely at your strongest and most energetic. However, ligament laxity may increase slightly, potentially increasing injury risk for dynamic movements.

Luteal Phase (Days 15-28)

Progesterone rises and dominates. Oestrogen drops initially then has a secondary rise before both hormones drop at the end. Core body temperature increases by 0.3-0.5 degrees. You may feel more fatigued, bloated, irritable, and prone to cravings. Training capacity may decrease.

Training Recommendations by Cycle Phase

During Your Period (Days 1-5)

How you might feel: Low energy, cramps, bloating, fatigue, mood changes.

What to do:

• Train if you feel up to it - exercise typically reduces period cramps by increasing blood flow and releasing endorphins
• Lower intensity if needed - reduce weights by 10-20%, focus on moderate rep ranges
• Prioritise movements that feel good: walking, yoga, light resistance training, swimming
• Gentle core work is fine - avoid high-pressure core exercises like heavy planks if you have severe cramps

What to skip:

• Don't force max-effort lifting on heavy period days if your energy is genuinely low
• Skip high-impact plyometrics if cramps are bad
• Don't feel guilty about a lighter session or a rest day on day 1 if you need it

Best exercises during your period:

• Brisk walking (20-30 minutes)
• Yoga - cat-cow, child's pose, and gentle stretching relieve cramp pain
• Light resistance training - machines are comfortable, goblet squats, dumbbell rows
• Swimming - the water pressure can actually reduce bloating and cramping

Late Follicular Phase (Days 6-14)

How you might feel: Increasingly energetic, strong, motivated. This is your peak performance window.

What to do:

• Push intensity - this is the time for heavy squats, deadlifts, and bench press
• Attempt personal records
• Higher volume training is better tolerated
• Introduce new skills or challenging exercises
• HIIT and intense cardio are well-suited to this phase

Training approach:

• 4-5 sessions per week if your schedule allows
• Progressive overload - add weight to the bar
• High-intensity interval training
• Complex movements requiring coordination (Olympic lifts, gymnastic progressions)

Ovulation (Around Day 14)

How you might feel: Strong and energetic, but potentially with slight joint instability.

What to do:

• Continue high-intensity training
• Be mindful of cutting and pivoting movements - ACL injury risk is slightly elevated around ovulation due to increased joint laxity from oestrogen peaks
• Warm up thoroughly, especially for dynamic lower body movements

What to be cautious about:

• Explosive direction changes (relevant for futsal, badminton, and court sports)
• Very heavy single-rep attempts without a proper warm-up

Luteal Phase (Days 15-28)

How you might feel: Gradually declining energy, increased body temperature, bloating, water retention, mood changes, cravings (especially for carbs and sweet foods).

What to do:

• Moderate intensity training - still train, but don't expect peak performance
• Higher reps with slightly lower weights
• Focus on hypertrophy-range work (8-15 reps) rather than max strength
• Steady-state cardio may feel more manageable than HIIT
• Stretching and mobility work - your body benefits from recovery-focused sessions

Training approach:

• 3-4 sessions per week
• Maintain your routine but adjust intensity based on feel
• Use RPE (Rate of Perceived Exertion) - if your usual weights feel like an 8/10 instead of a 6/10, that's the hormonal shift, not weakness
• Extra warm-up time - muscles and joints feel stiffer in this phase

Does Exercise Help Period Cramps?

Yes, for most women. Multiple studies confirm that regular exercise reduces the severity and duration of menstrual cramps. The mechanisms:

1. Endorphin release - natural painkillers produced during exercise
2. Increased blood flow - reduces pelvic congestion that contributes to cramping
3. Prostaglandin reduction - regular exercisers have lower levels of prostaglandins, the chemicals that cause uterine contractions (cramps)
4. Stress reduction - lower cortisol means less inflammation and less pain perception

The catch: you have to exercise consistently throughout the month, not just during your period. The protective effect comes from regular training habits.

Training With Menstrual Products

Pads

Fine for most gym training. May feel bulky during exercises with wide leg positions (sumo deadlifts, wide-stance squats). Wear dark-coloured shorts or leggings for confidence.

Tampons

Work well for all training types. Change before and after your session.

Menstrual Cups

Best option for gym training in my experience. No absorption-based issues, no shifting during movement, last up to 12 hours. Available in Malaysia from Shopee (RM30-80 for reusable cups like Lena Cup or Saalt).

Period Underwear

Increasingly popular. Brands like Modibodi and local Malaysian brands are available. Good for lighter flow days or as backup for a cup.

Nutrition Considerations Across the Cycle

Follicular Phase

• Insulin sensitivity is higher - your body handles carbs well
• Eat normally with adequate protein and carbs to fuel intense training

Luteal Phase

• Basal metabolic rate increases by 100-300 calories - you're genuinely hungrier, and your body needs more fuel
• Slightly increase calories (not dramatically - an extra snack or slightly larger meals)
• Cravings for sweets and carbs are hormonally driven. Instead of fighting them completely, satisfy them with healthier options: dark chocolate, fruit, yogurt with granola
• Magnesium needs increase - supplement with 200-400mg magnesium glycinate for cramp relief and better sleep

Iron Considerations

Menstruation causes iron loss. Women who train hard and have heavy periods are at elevated risk for iron deficiency anaemia. Symptoms: unusual fatigue, breathlessness during exercise, pale skin, cold hands and feet.

Eat iron-rich foods regularly: red meat, spinach, lentils (dal), tofu, and fortified cereals. Consider an iron supplement if blood work shows low ferritin levels.

Talking About Periods at the Gym

Malaysian culture can make discussing menstruation uncomfortable, especially in gym settings dominated by male trainers. If you work with a male trainer:

• A good trainer will have been educated about menstrual cycle training. If they dismiss your concerns or seem uncomfortable, that's a red flag about their professionalism.
• You don't need to share detailed information - "I'm in the lower energy phase of my cycle, so I'd like to adjust intensity today" is sufficient.
• Female trainers may be easier to discuss this with openly.

If you're a trainer reading this: educate yourself about menstrual cycle training. It affects half your potential clients, and being knowledgeable about it is a professional necessity, not optional.

The Bottom Line

Your period is not a reason to stop training. It's a reason to train smarter. Push hard during your follicular phase when hormones support performance. Ease off during the luteal phase when your body is working harder behind the scenes. Listen to your body, adjust accordingly, and maintain consistency throughout the month.

The women I've coached who sync their training with their cycle consistently outperform those who try to force the same intensity every single day regardless of where they are in their cycle. Work with your biology, not against it.
