Strength training is beneficial for people of all ages, with particular importance for older individuals. Resistance training helps to slow the decline in strength and muscle mass that occurs with aging. Adding resistance training to cardiovascular exercise can further reduce the risk of all-cause mortality. Strength training is also linked to better mental health and can help with weight management.
Highlights
Strength training is important for maintaining mobility and preventing a loss of physical function as we age.
The optimal frequency for strength training is at least twice a week, but three times a week may provide even better results.
The weight lifted during strength training is less important than reaching fatigue or close to failure.
Resistance training can have a positive impact on mental health and can be comparable to certain medications in reducing depression symptoms.
Building muscle through strength training can help with weight management, as muscle is a thermogenically active tissue that burns calories.

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
