The honest answer is that the best exercise for women changes depending on where you are in your menstrual cycle. This guide explains why, and how to match your training to your hormones for better results with less burnout.
If you search for the best exercise for women, you will find confident lists recommending strength training, HIIT, Pilates, or yoga. They are all right in certain contexts, and they are all incomplete without one crucial piece of information: where you are in your menstrual cycle.
Female physiology is not static. Oestrogen, progesterone, and testosterone fluctuate across a 28 to 35 day cycle, and these hormones directly influence your strength, endurance, recovery capacity, pain tolerance, and cardiovascular efficiency. An exercise that is genuinely optimal in week two of your cycle may actively work against you in week four.
Is Strength Training Good for Women?
Yes, and the research is clear on this. Resistance training is beneficial for women across all life stages. It increases bone density, improves metabolic health, reduces risk of injury, and builds functional strength that supports long-term quality of life. A 2019 analysis in the British Journal of Sports Medicine found that women who engaged in regular strength training had significantly lower all-cause mortality risk.
The nuance is timing. Women build muscle and recover from strength training significantly faster in the follicular phase (days 6 to 13) and ovulatory phase (around days 14 to 16) of their cycle, when oestrogen is high and supports muscle protein synthesis. Attempting heavy progressive overload in the late luteal phase (days 22 to 28) when progesterone dominates and recovery is slower tends to produce diminishing returns and higher perceived effort.
Is Cardio Good for Women?
Cardiovascular exercise benefits women at every fitness level, but the type and intensity should shift with the cycle. In the follicular and ovulatory phases, high-intensity cardio, interval training, and performance work are well-supported by hormonal conditions. In the luteal phase, steady-state cardio (a long walk, a moderate run, or a swim at comfortable effort) is more appropriate and tends to feel better.
One important note: studies have found that women are more susceptible to ACL injuries around ovulation due to oestrogen's effect on ligament laxity. This does not mean avoiding exercise at ovulation; it means warming up thoroughly and being particularly attentive to form and landing mechanics during high-impact activities in that window.
Is Yoga or Pilates Good for Women?
Both are excellent, and neither is a soft option. Pilates builds genuine core and posterior chain strength. Yoga improves mobility, reduces cortisol, and supports parasympathetic nervous system recovery. During the menstrual and late luteal phases, when the body is asking for less intensity, these forms of movement are often far more productive than pushing through a heavy training session on depleted hormonal resources.
The Best Exercise Framework for Women
Rather than asking which single exercise type is best, a more useful question is: which type of exercise suits the phase I am in today?
- Menstrual phase: yoga, walking, gentle stretching
- Follicular phase: strength training, HIIT, skill-based sports
- Ovulatory phase: peak performance work, strength, high-intensity cardio
- Early luteal phase: moderate strength, steady cardio
- Late luteal phase: Pilates, yoga, walking, light resistance
Apps like Solu make this framework practical by tracking your cycle phase and recommending movement types each day that match where your body actually is. Rather than trying to remember which week calls for which approach, you get a daily nudge that reflects your current hormonal context. Women who adopt this approach consistently report less training frustration, fewer missed sessions due to burnout, and stronger overall fitness progression.
