Fitness Over 40: Why Strength Training is the Key to Unlocking Your Best Self

Aging is inevitable, but feeling sluggish, stressed, and stuck in a fitness rut doesn’t have to be. For women over 40, staying fit isn’t just about looking good—it’s about feeling strong, moving well, and thriving despite the challenges that come with hormonal changes and increased life stress.

The Metabolism Myth: Why the Treadmill Isn’t the Answer

Many women turn to endless treadmill sessions in an attempt to “burn off” extra calories and rev up their metabolism. While cardio is great for heart health and stress relief, it’s NOT the most effective way to increase your metabolism and keep your body burning calories all day long.

Strength training is the game-changer. When you build muscle, your body requires more energy (calories) to maintain it. This means your metabolism naturally increases, and you continue burning calories even at rest—something cardio alone simply won’t achieve.

The Sullivan Personal Training Approach

At Sullivan Personal Training in Farmington, MO, we design strength training programs specifically for women over 40, helping them move better, feel stronger, and improve their overall health. Our programs focus on:


Core Strength – A strong core is essential for stability, posture, and injury prevention.
Power – Training explosive movements improves reaction time and overall strength.
Balance – As we age, balance declines. Training it now helps prevent falls and injuries later.
Full Body Strength – Building lean muscle across all major muscle groups keeps the body strong and functional.
Metabolic Conditioning – Short bursts of high-intensity strength training maximize fat burn and cardiovascular benefits.
Recovery – Proper mobility work and rest help your body perform and recover optimally.



Every workout at Sullivan Personal Training incorporates these elements in a way that’s tailored to your goals, experience, and limitations—so you get the most out of your fitness journey.
