Resistance training basics
Strength training principles need no special women's version: the same progressive overload, the same compound lifts, the same relationship between training volume and results. Individual differences belong in programming and recovery, not in whether to lift heavy.
Hypertrophy mechanisms
Waiting until the cut is over to start lifting gets the order backward: in a calorie deficit without mechanical tension, meaning muscles working against resistance, a sizable share of the weight you lose is muscle. Strength training tells the body that this tissue is still needed.

Osteoporosis
Heavy training makes bone stronger along the lines of load. In the LIFTMOR randomized trial (Watson 2018), 101 postmenopausal women with low bone mass did closely supervised high-intensity resistance and impact training twice a week for 30 minutes; after 8 months lumbar-spine bone density rose 2.9%, while the control group doing low-intensity exercise at home lost 1.2%. It was done in people with low bone mass under supervision, so get a professional assessment before starting on your own.
Sarcopenia
After menopause, muscle responds less to training and protein, and muscle loss speeds up. Regular strength training is the best-supported countermeasure; for protein, the PROT-AGE 2013 consensus advises at least 1.2 g per kilogram a day for adults over 65 who exercise regularly.
Endocrine
After puberty, men's blood testosterone is more than 15 times women's (Handelsman 2018), the main reason women build less muscle in absolute terms and do not easily turn bulky. The menstrual cycle is often said to make women stronger in the follicular phase and weaker in the luteal phase, but pooled across many people the difference is small, so adjusting to how you feel is enough.

Will lifting make women bulky?

Strength training will not give a woman a bodybuilder's bulk. What is missing was never training hard enough; it is that hormonal environment.

Testosterone is one of the strongest signals for muscle growth. From puberty on, men's blood testosterone is more than 15 times women's (Handelsman 2018, a review). So men start with more muscle and have a higher ceiling, and the same training adds fewer kilograms in women. Measured as a relative change, though, women respond to training just as well: in the pooled by Roberts 2020, muscle growth did not differ between men and women, and women's relative gains in upper-body strength were actually larger.

The look of the muscular women on social media comes from years of specialized training, very low body fat and sometimes hormones taken from outside the body — not from a few extra months in the gym. What strength training gives most women is more strength, more definition, and benefits for bone and metabolism.
