Good afternoon, Joel,
As a certified personal trainer, I've observed that pregnancy-related back strain is frequently linked to weight gain and the shift in gravity. However, I believe there are additional factors to consider:
Exercise: Could tailored exercises alleviate back strain during pregnancy?
Hormonal Changes: Might the hormone relaxin, known for loosening ligaments and joints, contribute to back strain?
Preexisting Conditions & Lifestyle: How might existing health conditions and lifestyle choices worsen back strain during pregnancy?
Psychological Factors: Could stress and changes in sleep patterns contribute to perceived back strain?
Gait Changes: How could alterations in movement patterns affect back strain, aside from gravitational shifts?
Explain one of the reasons why pregnant women often suffer from back strain late in their pregnancy.
