KEYPOINTS
- 01
Exercise science protocols for training, eating, and recovery are largely male-data generalised — women are not small men.
Dr Stacy Sims studies sex differences in exercise and nutrition. Couples doing identical training often see him lean out while she gains weight/slows — hormone profiles change intake and adaptation. Fasting/calorie restriction that works for many men often fails women differently.
- 02
By puberty, >60% of previously sporty girls drop out when body changes are not taught or affirmed.
Hips/shoulders widen, Q-angle changes, running/jumping feel alien. Without education on using female physiology as advantage, sport exits spike. Empowerment framing beats silence.
- 03
Women ~52% as strong upper body / ~66% lower vs men in book figures — trained women can reach ~70–80% of male strength.
Train accordingly without shame. Resistance training closes gaps meaningfully. Copying male programmes blindly ignores starting points and recovery.
- 04
ACL injury risk markedly higher in women — prevention protocols are mandatory, not optional.
Q-angle and neuromuscular patterns matter. Coaching must include ACL-prevention work as standard, especially adolescent females returning to sport.
- 05
Essential fat ranges differ (men ~4–8% vs women ~20% healthy framing) — stop copying male cut targets.
Female bodies need higher essential fat for health. Aesthetic cuts modelled on male influencers harm performance and hormones.
- 06
Nutrition timing and recovery cues must be sex-aware — male fasting wins do not transfer cleanly.
Hormonal cycles affect hunger and training response. Programme the calendar, not only the lifts.
- 07
Partners training together need different expectations and metrics.
Same plan, different physiology → different scoreboard. Compare to your baseline, not his mirror.
- 08
Teach girls what puberty does to sport feel — keep them moving through the awkward window.
Dropout is often information failure. Coaches and parents should normalise biomechanics talk early.
EXAMPLES
- 01
>60% sporty girls drop out around puberty framing.
Population exit crisis tied to untaught body change.
- 02
52% upper / 66% lower strength ratios; trained 70–80%.
Numbers for programming without shame.
- 03
Couple same-training divergent outcomes vignette.
Clinic pattern proving male protocols misfit.
- 04
Higher female ACL risk → mandatory prevention.
Safety non-negotiable in female sport.
- 05
Essential fat ~20% healthy female framing vs male single digits.
Anti-copy-male-cut rule.

If female, audit programme for male-default fasting, cuts, and recovery — adjust with sex-aware guidance.

Parents/coaches: educate girls through puberty biomechanics so they stay in sport.
Celebrate female physiology advantages explicitly.
- 03
Couples: stop identical plans as fairness — fairness is appropriate stimulus.
Track individual progress metrics.
