Strength training isn’t just about building muscles - it’s a powerful tool for mental health, especially for women. Research shows it can reduce depression by 30% and anxiety by 27%, thanks to its impact on stress hormones and brain function. Plus, it boosts confidence by focusing on what your body can achieve rather than how it looks.
Here’s how different exercises compare for mental well-being:
Strength Training: Reduces stress, improves self-esteem, and offers measurable progress.
Aerobic Exercise: Enhances mood, focus, and sleep through better oxygen flow to the brain.
Yoga/Mind-Body Practices: Promotes relaxation and emotional balance through mindful movement.
Combining these forms of exercise creates a balanced routine for mental resilience. Start with two strength sessions per week, add cardio for quick stress relief, and include yoga for mindfulness. Together, they build a stronger mind and body.

1. Strength Training
Strength training is unique because it offers clear, measurable progress. Adding just 5 pounds to a lift is tangible proof of growing strength, which can enhance confidence and reduce stress. This sense of achievement isn’t just psychological - it’s backed by biological changes.
Strength training directly impacts the hypothalamic-pituitary-adrenal (HPA) axis, helping regulate cortisol levels - the hormone closely tied to chronic stress and anxiety [5]. It also boosts Insulin-like Growth Factor 1 (IGF-1), which supports brain functions like learning, memory, and adaptability [5]. Interestingly, studies show that women may experience stronger anxiety-reducing effects from resistance exercises, particularly at low-to-moderate intensities (around 40–60% of their one-rep max) [5].
This type of exercise also shifts the focus from appearance to what the body can do, which creates a sense of empowerment [2]. This mindset shift is one reason why strength training ranks as the top activity for boosting feelings of accomplishment and empowerment in women [2]. Reflecting this trend, participation in weightlifting among women increased nearly five times between 2016 and 2022, signaling a broader move away from training solely for aesthetics [6].
Strength training benefits women across all stages of life. It builds self-esteem in adolescence, lowers the risk of postpartum depression, prevents muscle loss during perimenopause, and helps maintain independence in older age [2][4]. While gym memberships and equipment can be costly, bodyweight exercises like squats, lunges, and push-ups are excellent, no-cost starting points. Just two full-body sessions a week can deliver meaningful mental and physical improvements [2].
Compared to other workouts, Toned By Tony’s programs stand out by focusing on measurable progress and empowerment. These personalized strength training plans are designed specifically for women, emphasizing functional strength and steady progress to build both physical capability and mental resilience.
2. Aerobic Exercise
While strength training has its perks, aerobic exercise is another powerful tool for boosting mental health, especially for women. Activities like walking, jogging, dancing, and cycling are not only familiar but also require minimal equipment and are easy to incorporate into daily routines. Dr. Benjamin Snell, MD, a Family Medicine Physician at Penn Medicine, highlights the growing awareness of cardio's importance:
"Conversations about the number of steps people log each day have become so common that the importance of cardio exercise has filtered into our collective subconscious." [1]
This widespread recognition makes it easier to explore how different intensities and types of aerobic exercise can uniquely improve mental health.
From a biological perspective, aerobic exercise supports mental well-being in several ways. It helps regulate the HPA axis, enhances levels of BDNF (a molecule that promotes neuron growth), and improves blood flow and oxygen delivery to the brain. These effects are linked to better mood, sharper focus, reduced anxiety, and improved sleep. Neurophysiologist Toby Pasman sums it up:
"Better blood flow and oxygen to the brain is going to correlate to better mood, better focus, less anxiety, and better sleep." [7]
The intensity of aerobic activity matters, too. Moderate-intensity exercises, like brisk walking where you can still hold a conversation, are particularly effective for managing depression. On the other hand, low-intensity activities, such as gentle strolling or easy cycling, are better suited for reducing anxiety [9]. For those managing depression, the best results often come after 24 weeks or more of consistent effort [9].
Aerobic exercise is beneficial for women at any stage of life, but its effectiveness can vary depending on the group and activity type. For example, a meta-analysis found that while aerobic exercise reduces depression symptoms for postmenopausal women (SMD of -0.67), resistance training tends to deliver even greater benefits, with mind-body exercises also showing promise [8]. There's also an optimal "dose" for postmenopausal women: around 750 METs-min/week, with diminishing returns beyond 1,130 METs-min/week [8].
One of the standout features of aerobic exercise is its accessibility and adaptability. These qualities make it easier to stick to a routine and even foster social connections. A study of 400,000 adults revealed that 80% of women don't engage in regular weight training [11], suggesting that many already lean on cardio as their go-to exercise. Consistency is key - just 1–2 sessions per week can provide similar mental health benefits as three sessions [9]. For women in midlife, group-based activities like dance classes or running clubs add an extra layer of benefit. The sense of belonging created by group workouts enhances both biological and psychosocial well-being [9].
3. Mind-Body Practices (e.g., Yoga)
Mind-body practices like yoga, Pilates, and tai chi provide a pathway to mental clarity through slow, intentional movements. These rhythmic activities help calm the nervous system, promoting a sense of peace and relaxation [10].
One of their standout benefits is a mental "reset." Concentrating on breath and movement helps clear away mental distractions. Jacob Meyer, PhD, Assistant Professor at Iowa State University, highlights this distinction:
"While meditation and mindfulness give you a similar timeout from your thoughts, resistance training provides a different task to focus on and offers additional physiological adaptations... that meditation and mindfulness don't offer." [12]
While yoga excels at soothing the mind, it doesn’t stimulate the same biological responses - such as increased levels of BDNF (Brain-Derived Neurotrophic Factor) or IGF-1 (Insulin-like Growth Factor 1) - that strength training does. For women managing depression or anxiety, yoga works best as a complementary practice rather than a sole solution.
For women in midlife and beyond, these practices offer additional benefits, such as helping to manage mood swings and emotional reactivity during hormonal changes. They also contribute to an improved overall quality of life [10]. Practicing outdoors adds another layer of benefits, including reduced stress, improved mood, and enhanced body image and self-esteem, particularly in postmenopausal women [10]. These effects complement the mental resilience gained through strength and aerobic exercises.
Yoga’s gentler pace and social environment often appeal to women, making it a popular choice. Many initially turn to yoga for symptom relief, but its enjoyable and communal nature encourages long-term participation [10]. Andrew Brough, PT, DPT, CSCS, at Penn Medicine, emphasizes the importance of including flexibility movements in a well-rounded fitness plan:
"A good routine should include... flexibility movements such as yoga or stretching." [1]
Even occasional yoga sessions can meaningfully support mental health. When combined with strength and aerobic training, mind-body practices create a well-rounded approach to enhancing mental well-being.
Pros and Cons
Different types of exercise contribute to mental health in their own unique ways. The table below compares their strengths, challenges, and accessibility, offering a clear picture of how they support mental well-being.
Exercise Type | Mental Health Strengths | Limitations | Accessibility |
Strength Training | Reduces depression (~30%) and anxiety (~27%) [7]; builds empowerment and self-efficacy [2]; improves self-perception by focusing on functionality [6] | Requires proper technique; higher risk of injury without guidance; can feel intimidating in gyms [4] | High; bodyweight exercises or household items can be effective at home [14] |
Aerobic Exercise | Boosts mood instantly through endorphin release; provides rhythmic, meditative effects; lowers stress [13] | Excessive cardio may elevate cortisol; limited benefits for bone density and muscle retention [13] | Very high; activities like walking or running are low-cost and require no equipment [1] |
Yoga / Mind-Body | Reduces anxiety, promotes mindfulness, and fosters emotional grounding [14] | Lower metabolic demand; less effective at stimulating BDNF or reducing inflammation compared to strength training [7] | Very high; minimal space and no equipment needed [3] |
This comparison highlights that no single type of exercise can address every aspect of mental health. Strength training, for instance, provides the most biological benefits, including reducing C-reactive protein levels by ~20%, increasing BDNF (brain-derived neurotrophic factor), and stabilizing cortisol levels. A 2023 meta-analysis found that strength training outperformed aerobic, mixed, and mind-body exercises in improving depression and anxiety when done for 30–60 minutes per session, 3–4 times per week [7].
Aerobic exercise, on the other hand, offers immediate stress relief and is highly accessible, making it a great starting point for beginners or those with limited time. Meanwhile, yoga excels in fostering mindfulness and emotional balance, offering a calming complement to the physical and mental resilience built through strength training.
Combining these exercise types creates a well-rounded approach to mental well-being. Strength training builds resilience, aerobic exercise provides quick stress relief, and yoga nurtures a grounded, mindful state. Together, they form a powerful trio for enhancing mental health.
Conclusion
Strength training has emerged as a powerful tool for improving women's mental health. Research shows it can reduce depression by about 30% and anxiety by 27%. These results even surpass the benefits of aerobic and mind-body exercises, while also promoting a lasting sense of empowerment and self-control.
That said, no single type of exercise can fully address mental health needs. Strength training lays a solid foundation for both physical and mental well-being, but combining it with aerobic activities and yoga can create a more balanced routine. Aerobic exercise provides quick stress relief, while yoga enhances emotional stability. Together, these forms of movement complement each other, building a more resilient mindset.
A practical way to begin is by incorporating two to three full-body strength training sessions each week. For those just starting out, bodyweight exercises are a great entry point. Over time, you can gradually add resistance as your technique and confidence grow.

It focuses on functional strength training, personalized coaching, and flexible nutrition, helping you achieve progress in both your physical and mental health - without the risk of burnout.
FAQs
How soon will strength training help my mood?
Strength training has a way of lifting your spirits almost instantly. After just one session, many people report feeling less anxious and mentally sharper. Stick with it regularly, and the perks only grow - things like reduced symptoms of depression and better overall mental health become more apparent as time goes on. The secret? Staying consistent to keep those positive changes coming.
What’s the safest way to start lifting if I’m a beginner?
If you're new to lifting, the safest approach is to begin with two full-body workouts per week. This gives your muscles time to recover while helping you build a solid foundation. Focus on proper form above all else - this is key to avoiding injuries and making steady progress.
Start with light to moderate weights or even resistance bands. The goal is to master your technique before adding heavier loads. If you're unsure about your form, working with a qualified trainer or following a beginner-friendly program can make a big difference.
Pay attention to your body. If you experience pain or discomfort, stop immediately and consult a professional. Listening to your body is just as important as the exercises themselves.
How do I combine strength, cardio, and yoga without burnout?
To keep burnout at bay, try sticking to a balanced weekly workout plan that assigns specific days to different types of activities. For instance, you could aim for 3 strength training sessions, 3 cardio workouts, and 3 yoga or mobility sessions each week. Spread out your intense workouts, make room for rest days, and pay attention to how your body feels. This method not only supports long-term consistency but also helps you maintain both physical and mental balance, making your routine enjoyable while steering clear of overtraining.
