Do women have to lift heavy to see results? Will we get the same results from lifting light weights? In today's episode we dive into the science behind lifting weights and how age and hormones play a factor in the type of strength training we should be doing.
After age 35, we naturally lose muscle unless we actively train to keep it. Less muscle = slower metabolism. That’s why strength training is non-negotiable!

Do women have to lift heavy to see results? Will we get the same results from lifting light weights? In today's episode we dive into the science behind lifting weights and how age and hormones play a factor in the type of strength training we should be doing.
After age 35, we naturally lose muscle unless we actively train to keep it. Less muscle = slower metabolism. That’s why strength training is non-negotiable!
Declining Estrogen & Progesterone – Estrogen helps with muscle recovery. As levels decline, recovery slows.
Lower Testosterone – Testosterone is essential for muscle-building. As it decreases, it’s harder to maintain muscle. This is why lifting heavy won’t necessarily make you bulky (with good exercise selection)!
Fluctuating Cortisol – Higher stress = higher cortisol, which can lead to muscle breakdown and fat storage. Managing stress and including low-intensity steady-state cardio (like walking) helps keep cortisol in check.
Research confirms that Lifting light with high reps (at 30% of your one-rep max) is just as effective as lifting heavier with lower reps (at 70-80% of your one-rep max). Let's get into it!
